The Kansas City Chiefs confirmed Mahomes had successful surgery with Dr. Dan Cooper. The team said rehab will begin right away, but no return date was shared. NFL Network’s Ian Rapoport reported the added LCL tear does not guarantee a longer rehab. Still, it adds another layer to the process and raises questions about timing.

Mahomes was injured as he was chased from behind and got tangled up with Chargers lineman Da’Shawn Hand. Mahomes immediately grabbed his knee after it buckled and eventually needed help from two Chiefs staffers to walk to the locker room. The Chiefs have three games remaining in the season.

Mahomes’ knee buckled on a tackle in the final two minutes of Kansas City’s loss to Los Angeles. The quarterback remained down holding his knee before he was helped to the locker room. Video showed him unable to put much weight on his left leg.

Patrick Mahomes' season is over with a torn ACL, and the same is feared for Micah Parsons. The injury bug made an unwelcome appearance during Week 15 in the NFL, striking two superstars just hours apart.

Patrick Mahomes underwent surgery on Monday night to repair a torn ACL in his left knee. It wasn’t the only ligament injured, after all. Via Ian Rapoport of NFL Media, Mahomes also tore the LCL in his left knee. Rapoport adds that, while it complicates the recovery, it doesn’t necessarily extend the timeline for a return beyond nine months.

Athletes are typically able to return from ACL tears within 6-12 months. Tom Brady's recovery from an ACL tear offers the most optimistic outlook for what Mahomes could expect.
