Kansas City Chiefs vs Buffalo Bills Match Player Stats: Josh Allen’s Historic Night Leads Bills to 28–21 Victory

Searching for the complete Kansas City Chiefs vs Buffalo Bills match player stats from one of the most statistically lopsided performances in this storied rivalry? Patrick Mahomes just posted the worst completion percentage of his nine-year NFL career — 44.1% — while Josh Allen answered with an 88.5% completion rate that broke the Buffalo Bills franchise record. The numbers don’t lie: this was a performance breakdown that demands a full breakdown.

The Lead: How Buffalo Dismantled the Defending Champions

On a crisp November afternoon at Highmark Stadium in Orchard Park, New York, the Buffalo Bills put on a masterclass in efficient, balanced football to defeat the Kansas City Chiefs 28–21 in a Week 9 NFL regular season showdown. Before an electric crowd of 71,024 fans on November 2, 2025, the Bills controlled virtually every facet of the game — time of possession, yardage, turnover margin, and quarterback efficiency — to hand the two-time defending Super Bowl champions their fourth loss of the season.

Josh Allen orchestrated the victory with ice-cold precision: 23-of-26 passing for 273 yards, one touchdown pass, two rushing touchdowns, and a passer rating of 123.2. On the other sideline, Mahomes was under siege all afternoon. Sacked three times, hit 15 more, and completing barely four of every nine attempts, the Chiefs’ franchise quarterback endured the worst statistical outing of his professional life.

Buffalo’s defense set the tone from the first snap and never let Kansas City find its rhythm. When rookie cornerback Maxwell Hairston batted away Mahomes’ final desperation heave with 22 seconds left, the game — and the AFC’s early power dynamic — was officially decided.

Match Overview Table

Core Match Statistics Overview

Team Stats Comparison

Quarterback Efficiency

The gap in passing efficiency was the defining statistic of the afternoon. Allen’s 123.2 passer rating against Mahomes’ 57.2 represents a 66-point differential — almost unthinkable when these two elite signal-callers square off.

• Allen’s 10.5 yards per attempt dwarfed Mahomes’ 7.4, revealing that every time Allen released the ball, the Bills gained significantly more ground per rep.
• Mahomes’ 44.1% completion rate wasn’t just a bad day — it was statistically the worst of his entire NFL career, and the first time he ever completed fewer than half his passes in a regular-season game across nine seasons.

Ground Game Dominance

Buffalo’s rushing attack was the engine that kept the game clock moving and the Chiefs’ pass rush fatigued by the fourth quarter.

• James Cook III’s 114 rushing yards on 27 carries, combined with Allen’s two rushing touchdowns, gave Buffalo 141 total ground yards against just 79 for Kansas City.
• The Bills’ 34:45 time of possession — nearly 10 minutes more than the Chiefs — was a direct result of their ability to move the chains on the ground.

Turnover Battle

The single turnover margin proved decisive in a game decided by one score.

• Mahomes’ first-quarter interception, snagged by rookie Maxwell Hairston in just his second career NFL game, immediately handed Buffalo prime field position and set the tone.
• The Chiefs’ kicking unit also hurt them late: Matt Prater’s missed 52-yard field goal attempt with under a minute remaining gave Kansas City one final chance they couldn’t convert.

Pressure and Sacks

Buffalo’s defensive front held a critical statistical edge in disruption metrics.

• Bills defenders registered 15 quarterback hits on Mahomes throughout the afternoon — a number that clearly affected his decision-making and release timing.
• Joey Bosa (1 sack, 5 QB hits) and Christian Benford (1 sack) led the Buffalo pass rush, while the Chiefs’ Chris Jones and George Karlaftis combined for 1.0 sacks on the other side without the same systemic disruption.

Period-by-Period Analysis

First Quarter — Bills Strike First

• Josh Allen found the end zone on the ground in the opening period, capping a methodical opening drive that burned clock and set the physical tone Buffalo wanted.
• Mahomes was intercepted by Maxwell Hairston — the rookie cornerback’s first career pick — ending Kansas City’s first meaningful possession and giving the Bills early momentum.
• The Chiefs’ offense struggled to find any consistency in the opening 15 minutes; zero points and a giveaway put them in an early 7–0 hole against a team playing with enormous home-crowd energy.

Second Quarter — Bills Extend, Chiefs Rally

• Kansas City’s offense woke up in the second quarter, posting 13 points — including a Kareem Hunt rushing touchdown and two Harrison Butker field goals — to temporarily make the game competitive.
• Dalton Kincaid was the standout Bills weapon in the period, hauling in multiple receptions on the way to a six-catch, 101-yard, one-touchdown performance that broke the Chiefs’ zone coverage all afternoon.
• Buffalo scored 14 second-quarter points of their own — the higher-output half of the game for both offenses — to hold a commanding 21–13 advantage at halftime.

Third Quarter — Bills Extend, Chiefs Go Silent

• The third quarter belonged entirely to Buffalo. Josh Allen added another rushing score, and the Bills’ defense completely shut out Kansas City’s offense for the entire 15 minutes.
• Mahomes was unable to generate any sustained drives as the Bills’ defensive scheme — heavy on Cover-2 shell looks with aggressive interior pressure — disrupted the Chiefs’ timing routes.
• James Cook III’s consistent gains on the ground in this period kept the Buffalo offense on schedule and prevented Kansas City from getting favorable field position via short drives.

Fourth Quarter — Chiefs Too Little, Too Late

• The Chiefs scored 8 points in the fourth quarter — a touchdown (Rashee Rice rushing TD plus a two-point conversion) — to make the score 28–21 with enough time for one final drive.
• Matt Prater’s missed 52-yard field goal attempt gave Mahomes one last shot from his own 42-yard line with 22 seconds remaining, but Cole Bishop (pass breakup on second down) and Maxwell Hairston (final deflection) sealed the win.
• Buffalo’s offense went quiet in the fourth, gaining zero points — but a 28-point lead meant the Bills could sit back and let their defense close things out.

Buffalo Bills Player Statistics

Josh Allen — QB

Josh Allen was the unambiguous MVP of this matchup, delivering a performance that will be remembered in Bills history. His 88.5% completion rate shattered the franchise record, and his two rushing touchdowns underscored his dual-threat nature that Mahomes simply couldn’t match on this afternoon. Allen absorbed three sacks but refused to let the defensive pressure affect his rhythm, finishing with an otherworldly passer rating of 123.2 against the reigning AFC champions.

James Cook III — RB

Cook was the workhorse Buffalo needed to control the clock and keep Kansas City’s offense off the field. His 27-carry, 114-yard afternoon gave the Bills’ ball-control attack a physical presence that consistently moved the chains on first and second down. By the third quarter, Kansas City’s front seven was visibly fatigued from pursuing Cook all game long.

Dalton Kincaid — TE

Kincaid ran perfect routes against a Kansas City defense that simply had no answer for the tight end’s combination of size and release quickness over the middle. His 6-for-6 target-to-catch rate was a microcosm of the Bills’ entire offensive efficiency on the day — every throw placed, every route run with intent. His 47-yard gain down the right sideline was the play of the game that buried the Chiefs defensively.

Khalil Shakir — WR

Shakir was Allen’s security blanket and chain-mover throughout the afternoon. While his yardage total was modest, his seven receptions on eight targets — a 87.5% catch rate — helped Allen maintain that elite completion percentage. Shakir consistently picked up first downs in the intermediate zones that Kansas City’s defense left open when selling out to stop Cook.

Kansas City Chiefs Player Statistics

Patrick Mahomes — QB

Mahomes’ afternoon was a study in compounding problems. The Bills’ defensive pressure disrupted his timing, the Bills’ secondary played with unusual physicality at the line of scrimmage, and the safety help over the top eliminated his deep throw opportunities. Completing just 44.1% of his passes was uncharted territory for a quarterback who had never dipped below 50% in a regular-season game across his entire career before Sunday.

Rashee Rice — WR

Rice was Mahomes’ most reliable weapon all afternoon, consistently winning on short-to-intermediate routes while posting the team’s highest receiving yardage total. His rushing touchdown late in the fourth quarter — part of the two-score burst that almost made things interesting — showed his versatility as a weapon around the goal line. But on 7 targets, converting just 4 catches speaks to the Bills’ ability to contest his routes when it mattered most.

Travis Kelce — TE

Travis Kelce’s stat line was functional but ultimately quiet by the standard that makes him the greatest tight end in NFL history. Four receptions for 66 yards on five targets represents the Bills’ defensive scheme working exactly as designed — limit Kelce’s touches, force Mahomes to win with his less proven supporting cast. Buffalo’s linebackers tracked Kelce with unusual discipline all afternoon, never losing him in zone coverage as teams routinely do.

Kareem Hunt — RB

Hunt was Kansas City’s most consistent offensive contributor on the ground, producing their lone rushing touchdown in the second quarter. His 4.5 yards per carry average was respectable against a Bills front seven playing with physicality and energy. But 11 carries for 49 yards wasn’t enough volume to keep the Buffalo defense honest or control the clock the way Cook did on the other sideline.

Statistical Leaders Summary Table

Analytical Breakdown: Why They Won / Why They Lost

Why the Buffalo Bills Won

Elite Quarterback Efficiency

The Bills’ offensive game plan was built around getting the ball out quickly and accurately. Allen’s 10.5 yards per attempt — compared to Mahomes’ 7.4 — meant Buffalo generated more offense with fewer possessions. Going 23-for-26 with zero interceptions against a Chiefs defense that entered the game with six interceptions on the season is a remarkable statistical achievement.

Ground-and-Pound Time of Possession

Buffalo’s ability to run the ball effectively — 141 yards on 35 carries — translated directly into nearly 10 extra minutes of possession time. The Chiefs had just 25:15 with the ball, meaning their offense faced a constant uphill battle to generate drives before fatigue set in late in the game.

Defensive Disruption of Mahomes

Buffalo’s front seven generated 15 quarterback hits and three sacks in a systematic assault on Mahomes’ launch timing. Joey Bosa’s five QB hits alone were more than any individual Chief managed against Allen (three total sacks allowed).

• Cole Bishop led the secondary with 4 pass breakups, shutting down the deep ball that Mahomes desperately needed.
• The Bills held Kansas City’s vaunted passing attack to zero touchdown passes for the first time in 23 regular-season games.

Clean Ball Security

Zero turnovers against an opponent that had just taken Josh Allen to an AFC Championship and won. Every Buffalo possession was preserved, giving the Bills a significant possession-efficiency edge throughout the game.

Why the Kansas City Chiefs Lost

Mahomes Under Siege All Afternoon

The Chiefs’ offensive line failed to give Mahomes clean pockets consistently. Three sacks and 15 hits added up to a broken rhythm that Kansas City’s typically reliable play-action and bootleg game never recovered from.

Zero Passing Touchdowns

Perhaps the most damaging single stat of the day: Mahomes failed to throw a touchdown pass for only the third time in his 2025 season. With a lead-footed running game (79 total yards), the Chiefs needed Mahomes to create magic in the passing game — and he simply couldn’t on this afternoon.

Special Teams Miscue at a Critical Moment

Matt Prater’s missed 52-yard field goal with under a minute remaining — his only attempt of the day — handed Mahomes the ball one last time. Had the kick split the uprights, the score would have been 28–24 and a Kansas City touchdown would have won the game outright. Instead, the momentum swing set up a frantic final sequence the Chiefs couldn’t complete.

Historical Context & Advanced Insights

Bills vs. Chiefs 2025 Season Series Breakdown

The January 2025 AFC Championship — a 32–29 Chiefs win at Arrowhead that sent Kansas City to Super Bowl LX — was still fresh in both locker rooms when November’s meeting arrived. Buffalo came in with a point to prove that Allen’s near-perfect regular-season performances translate to playoff-caliber domination.

Bills–Chiefs All-Time Rivalry Overview

While the Bills hold the all-time series edge at 31–26–1, the Chiefs have dominated postseason play 5–2, including four consecutive playoff victories from 2020 through 2025. Buffalo’s Week 9 win offers evidence that the regular-season balance is shifting — but the Bills will need to replicate this level of performance when it counts most in January.

Advanced Statistical Insights

Assist-to-Completion Ratio: Josh Allen targeted nine different receivers, completing passes to ten of them with zero wasted targets — a sign of offensive diversity that makes him nearly impossible to scheme against. Mahomes, by contrast, relied heavily on Rashee Rice (7 targets) and Travis Kelce (5 targets), with 13 of his 34 attempts finding no receiver at all.

Pressure-to-Rating Conversion: The Bills generated 15 pressures and converted them into a 44.1% completion rate from Mahomes. That works out to roughly one significant disruption every 2.3 dropbacks — and the compounding effect on a quarterback who typically thrives on extended plays was visually evident throughout the game.

Rushing Efficiency Impact: When teams run the ball effectively in the NFL (4.0+ yards per carry), they historically win 64% of those games. Both teams hit the 4.0 per-carry threshold, but Buffalo’s 75-play script versus Kansas City’s 57-play script meant the Bills generated 12% more offensive actions, with each possession given a higher statistical probability of scoring.

Game Implications & Key Lessons

What This Means for the Buffalo Bills

• Buffalo moved to 6–2 on the season and opened a 2.5-game edge over the Chiefs (5–4) in the AFC playoff standings, strengthening their case for a home playoff game.
• The win demonstrated that Allen and this Bills offense are capable of the kind of near-perfect efficiency needed to beat a Chiefs team that has historically found ways to out-execute Buffalo in big moments.
• The Bills’ defense, long considered the team’s potential weak link, posted its most complete performance of the season — limiting the two-time defending champions to zero passing touchdowns and forcing a career-worst day from Mahomes.

What This Means for the Kansas City Chiefs

• At 5–4, the Chiefs face a genuine AFC playoff seeding challenge. Their schedule toughens down the stretch, and another loss or two could push them to a wild-card berth rather than a top seed.
• Mahomes’ first career sub-50% completion game raises questions about the Chiefs’ offensive line health and whether the receiving corps — led by Rashee Rice and an aging Travis Kelce — can consistently create the separation Mahomes needs when protection breaks down.
• The missed Prater field goal was ultimately peripheral to the game’s outcome, but it signals that special teams — a traditionally reliable Kansas City strength — needs attention heading into the second half of the season.

Key Lessons from Bills 28, Chiefs 21

• Completion percentage is a quarterback efficiency multiplier: Allen’s 88.5% vs. Mahomes’ 44.1% was effectively a 44.4-point gap in one of football’s most telling single-game metrics.
• Time of possession is an offensive weapon: Buffalo’s nine extra minutes with the ball translated directly into a 99-yard total yardage edge.
• Rookie defensive backs can change games: Maxwell Hairston — playing just his second NFL game — recorded the decisive interception and the game-sealing deflection, bookending one of the Chiefs’ worst offensive performances.
• Ground game diversity wins the field: With Cook as the featured back and Allen as a constant rushing threat, Buffalo presented a two-dimensional run game that Kansas City had no clean solution for.
• Zero turnovers against elite competition: In the Chiefs’ four most recent wins over the Bills (all in the postseason), Buffalo committed multiple turnovers in each. The Bills’ turnover-free performance was the clearest indicator of how this game ended differently.
• Missed special teams moments compound quickly: Prater’s 52-yarder miss gave Kansas City a final drive they couldn’t convert — a reminder that in seven-point games, special teams rarely provide neutral outcomes.
