Since 2018, the Chiefs lead the league with three games with zero accepted penalties. There have been 40 such games overall since 2000.

A cliche often heard from NFL coaches is that one of the keys to winning is not beating yourself with self-inflicted errors. In the Kansas City Chiefs’
30-17 win over the Detroit Lions on Sunday night, the Chiefs came out unscathed in that regard in rare fashion.
The Chiefs became the first team since 1972 to have zero accepted penalties, zero turnovers and no more than one punt in a game, according to NBC’s “Sunday Night Football” broadcast. On paper, it was one of the cleanest games in NFL history.
Unlike the efficiency on offense, the penalties are not entirely in the control of the teams playing. Though players can do their part in not committing a penalty, an official’s judgment is very much part of the equation. It’s not uncommon for referees to miss calls or inadvertently call a penalty when there may not have been anything illegal.
In the minds of some Lions players, perhaps the officials were a little too easy on the Chiefs. The end of the game was
marred by a brawl incited by Lions defensive back Brian Branch, who expressed his frustration with the officiating after the game.
“I did a little childish thing,” said Branch, who started the brawl after refusing to shake hands with Chiefs quarterback Patrick Mahomes and then shoving receiver JuJu Smith-Schuster in the face, “but I’m tired of people doing stuff in between a play and refs don’t catch it. Like them trying to bully me out there. Should’ve never did it. It was childish.”
The Lions' Brian Branch appeared to kick off the melee with a slap, and even three-time Super Bowl winner Patrick Mahomes got involved.
The play Branch appeared to be referring to
occurred in the waning minutes of the Chiefs’ victory, when Smith-Schuster shoved him to the ground away from the play on a run up the middle.
“I got blocked in the back illegally, and it was in front of the ref, and the ref didn’t do anything,” Branch said.
Other plays were circulating after Sunday’s game that indicated missed calls against the Chiefs, including Mahomes
appearing to taunt Branch after a short touchdown run and
an apparent hold by Travis Kelce on a swing pass in the fourth quarter.
Sunday night’s game wasn’t a highly penalized affair overall. The Chiefs were called for their first penalty of the evening 57 minutes into the game when defensive tackle Chris Jones jumped offsides, but the Lions declined the penalty after Jared Goff completed a 9-yard pass to Sam LaPorta on the play.
The Lions ended the game with four penalties for 38 yards. Two of those penalties occurred concurrently when, after some discussion, Detroit was penalized for
illegal motion in the first quarter on a touchdown pass from running back David Montgomery to Goff. The Lions then took a delay of game before kicking a field goal. In the second quarter, the Lions were flagged for pass interference, and in the fourth quarter, Detroit was called for roughing the passer. Both drives ended in Chiefs touchdowns. The Lions were called for two other penalties — both defensive offsides — but those penalties were declined.

Kansas City’s zero-accepted-penalties game is the first of its kind across the NFL since the final week of the 2023 season. On Jan. 17, 2024, the Seattle Seahawks and Las Vegas Raiders each had zero accepted penalties in their wins over the Arizona Cardinals and Denver Broncos. Since 2000, that’s the only day in the NFL that featured multiple teams on the same day having games without an accepted penalty. In Week 16 of the 2011 season, the Tennessee Titans and Green Bay Packers also had zero-penalty games, although they came one day apart.
Since 2000, there have been 40 games in which a team didn’t have a single accepted penalty, according to TruMedia. Those teams are 25-15 in those games.
In the Mahomes era, Kansas City has had three games when it did not have an accepted penalty, and the Chiefs are 3-0 in those contests. That includes a 2019 game against the Raiders in which Las Vegas committed 12 accepted penalties. That’s the largest accepted penalty difference in any of those 40 games since 2000 in which one team wasn’t flagged. (Overall, since 2000, 17 penalties is the largest accepted penalty difference in any game, per TruMedia. The Raiders were also on the wrong side of that one when they had 23 accepted penalties to the Tampa Bay Buccaneers’ six, although the Raiders won that 2016 game in overtime.)
The Chiefs’ three penalty-free games are the most in the NFL since 2018, but four teams (the Raiders, Seahawks, Philadelphia Eagles and Green Bay Packers) have had two such games in that stretch.
In the Mahomes era, the Chiefs have been on the other end of a zero-penalty game twice. The first time was in Mahomes’ first year as a starter in 2018, when the New England Patriots rode a penalty-free game to a 43-40 win. In 2023, the Raiders didn’t commit an accepted penalty against the Chiefs (Kansas City had four penalties for 40 yards in that game), but the Chiefs still won 31-17.
In recent history, officiating has been a heavy point of dialogue in regards to the Chiefs, from
Kansas City’s own gripes, to Mahomes’ way of
baiting defenders to draw penalties, to the outright
theory that officials favor the Chiefs.
However, entering Week 6, only three teams had more accepted penalties this season than the Chiefs. Since Mahomes became a starter in 2018, the Chiefs rank in the top 10 of the league in accepted penalties.
