when did mahomes get hurt

Patrick Mahomes most recently suffered a major knee injury on December 14, 2025, late in a Week 15 game against the Los Angeles Chargers.

Quick Scoop

• In that Chargers game, Mahomes tore the ACL in his left knee in the closing minutes of the fourth quarter.

• The injury happened as he was pressured, planted on his left leg, and his knee buckled while he threw the ball away.

• Reports note he immediately grabbed his left knee, stayed down, and was checked by trainers on the sideline.

• The team later confirmed it as a torn ACL that ended his 2025 season and put his availability for the start of the next season in doubt.

A bit of context

• Earlier in his career, Mahomes had a notable knee injury in 2019, when he dislocated his right kneecap on a quarterback sneak on October 17, 2019, but missed only two games.

• He also played through high ankle sprains and turf toe in previous playoff runs, but those did not knock him out for an extended stretch like the December 2025 ACL tear.

TL;DR: If you are asking “when did Mahomes get hurt” in terms of the big recent one, it was December 14, 2025, versus the Chargers, when he tore his left ACL late in the game.
