Championship Dynasty Derailed by Devastating Injury
Patrick Mahomes suffered a torn ACL in his left knee during the waning seconds of the Chiefs’ 16-13 loss to the Los Angeles Chargers on Sunday, December 14, 2025. The injury occurred when Mahomes scrambled toward the sideline and was spun to the ground by Chargers defensive lineman Da’Shawn Hand.
The 30-year-old quarterback immediately grabbed his knee and required assistance to reach the locker room, where an MRI confirmed the worst fears of Chiefs Kingdom.

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.

First Playoff Miss Under Mahomes Leadership
The loss to the Chargers, combined with victories by Jacksonville, Buffalo, and Houston, eliminated the defending AFC champions from playoff contention. This marks the first time in Mahomes’ seven seasons as starter that Kansas City will miss the postseason.
The quarterback who has led the Chiefs to three Super Bowl titles and seven consecutive AFC championship appearances now faces his longest rehabilitation period. Mahomes won’t return to the field until sometime in 2026.
Injury Crisis Cripples Championship Offense
The Chiefs entered the crucial game decimated by injuries across their offensive line and skill positions. Left tackle Josh Simmons was on injured reserve with a fractured wrist, while backup Wanya Morris and right tackle Trey Smith were sidelined with knee and ankle injuries respectively.
During the game, backup right tackle Jaylon Moore also suffered a knee injury, forcing journeyman players and practice squad members to protect Mahomes. The offensive line collapse left the quarterback vulnerable to the hit that ended his season.
Mahomes Vows Comeback Despite Setback
Following the diagnosis, Mahomes posted on social media expressing his determination to return stronger. “Don’t know why this had to happen, and not going to lie it hurts. But all we can do now is trust in God and attack every single day over and over again,” the two-time MVP wrote.
Backup quarterback Gardner Minshew attempted to rally the team in the final moments but threw an interception to Derwin James with 14 seconds remaining, sealing the Chargers’ season sweep of Kansas City.
Historic Durability Record Comes to an End
The torn ACL represents the most significant injury of Mahomes’ nine-year career, surpassing his 2019 dislocated kneecap and 2022 high ankle sprain during the playoffs. His previous injury resilience had become legendary among Chiefs fans, particularly after he played through the ankle injury to lead Kansas City to a Super Bowl victory.
Defensive tackle Chris Jones, who also battled through injuries during the game, embraced his teammate afterward, saying “That’s my brother. We’ve been through so much. We love Pat.”
