Devastating Injury Ends Championship Dreams
Patrick Mahomes sustained a torn ACL in his left knee during the final moments of Kansas City’s 16-13 defeat to the Los Angeles Chargers on December 14, 2025. The 30-year-old quarterback was scrambling toward the sideline when Chargers defensive lineman Da’Shawn Hand spun him to the ground, causing immediate damage to his knee.
Mahomes grabbed his left knee instantly as trainers rushed to assist him, eventually helping him to the locker room with a towel over his head.

Left knee hyperextendeds while slightly laterally rotated.
I’m hoping it wasn’t enough excursion for an ACL or PCL but those will be assessed for.
LCL and posterolateral corner are also concerns.

Historic Career Derailed by Freak Accident
The injury represents the most significant setback of Mahomes’ remarkable nine-year career, which includes three Super Bowl titles and seven consecutive AFC championship game appearances.
The two-time MVP had previously avoided major injuries, with his worst being a 2019 kneecap dislocation and a 2022 high ankle sprain during the playoffs. This ACL tear will sideline him until sometime in 2026, marking the first time in his starting career that Kansas City will miss the playoffs entirely.
Team Decimated by Injury Epidemic
Kansas City entered the game already severely compromised by injuries across both sides of the ball. The offensive line was missing left tackle Josh Simmons, backup Wanya Morris, right tackle Trey Smith, and saw Jaylon Moore injured during the game.
This forced inexperienced players like Chukwuebuka Godrick, who had never appeared in an NFL game, to protect Mahomes. Wide receivers Marquise Brown, Tyquan Thornton, and Xavier Worthy all missed significant time due to various injuries and concussion protocols.
Championship Dynasty Faces Uncertain Future
Gardner Minshew replaced the injured Mahomes and completed three consecutive passes before throwing a crucial interception to Derwin James with 14 seconds remaining, sealing the Chiefs’ elimination from playoff contention.
The loss, combined with victories by Jacksonville, Buffalo, and Houston, officially ended the defending AFC champions’ season.
Mahomes posted on social media expressing his faith and determination to return stronger, while teammates like Chris Jones emphasized the emotional impact of losing their franchise quarterback during such a critical moment.
