The Chiefs' quarterback was hurt in the closing minutes of Sunday's loss to the Los Angeles Chargers, which ended the Chiefs' decadelong streak of making the postseason.

Mahomes' surgery was performed by Dr. Dan Cooper, the Dallas Cowboys' team physician and a well-known orthopedic surgeon.

Mahomes, a two-time MVP and three-time Super Bowl champion, suffered the knee injury in last Sunday’s loss to the rival Los Angeles Chargers. At 6-8, the Chiefs are already guaranteed to miss the postseason for the first time since 2014 and are at risk of their first losing season since 2012.

The Kansas City Chiefs’ stunning fall has turned one of the NFL’s most dominant dynasties into a cautionary tale. Just one season after a 15-2 campaign, the Chiefs are now 6-8 and officially out of playoff contention.
