The Kansas City Chiefs suffered a disappointing Week13 loss, falling to the Dallas Cowboys with a 31-28 final score on Thanksgiving Day.

The loss marked the Chiefs’ third in the last four games, dropping their 2025 season record to 6-6. The reigning AFC champions are now in danger of missing the postseason as they head into the final stretch of the year.

With just over 13 minutes remaining in the third quarter, Chiefs running back Isiah Pacheco reeled in a screen pass from quarterback Patrick Mahomes. The 26-year-old ball-carrier lowered his helmet and delivered a hit on Cowboys cornerback DaRon Bland as he went out of bounds before the line to gain on a 3rd-and-16 play.

On Saturday afternoon, the NFL announced a $46,371 fine for Pacheco for “impermissible use of the helmet.”

The first-offense fine is $23,186, which elevates to $46,371 upon a second offense. Pacheco’s fine was the largest of Week 13, which yielded 29 total fines.

Week 13 marked Pacheco’s first return to the field for the Chiefs since suffering a knee injury against the Washington Commanders in Week 8. Kansas City’s former starting running back had just thee carries for 16 yards in the Thanksgiving Day loss, ceding the vast majority of RB touches to veteran ball carrier Kareem Hunt.

The Chiefs dropped their sixth loss of the 2025 season despite a masterful performance from Mahomes, who finished the game with 261 yards, four touchdowns and zero interceptions on 23 of 34 passing. The dual-threat QB out-gained Pacheco on the ground, recording 30 yards on three carries.

The Chiefs, who essentially need to win out to earn a playoff berth, will look to get their 2025 season back on track in a Week 14 matchup against the Houston Texans on Sunday night.
