A worrying diagnosis
Patrick Mahomes tried to escape pressure when his left knee gave out. Former NFL doctor David J. Chao explained that video replays revealed a multi-ligament injury from the start. The speed of the surgery was another sign it wasn’t just an ACL tear.
The specialist noted that the same surgeon had handled similar cases for Jaylon Smith and Travis Hunter. That detail reinforced the idea that Patrick Mahomes faces a longer, more demanding process.

Comparisons and context
Patrick Mahomes was compared to Micah Parsons, who also tore a ligament that same week. However, the Green Bay defender didn’t undergo immediate surgery, highlighting how Mahomes’ case is more complex.
Chao stressed that multi-ligament injuries require discipline and patience. Still, he offered hope. Patrick Mahomes could be ready for next season if rehab goes smoothly.
The Chiefs’ future
Patrick Mahomes finished the year with 3,587 passing yards, 22 touchdowns, and 11 interceptions in 14 games. Those numbers underline his impact despite the team’s struggles.
Yet the Chiefs now face months without their leader and uncertainty about how his knee will respond. Head coach Andy Reid remains optimistic, but he knows recovery will shape the franchise’s direction. For Kansas City, the priority is no longer this season—it’s ensuring Patrick Mahomes returns at full strength to compete at the highest level of the NFL.
