Even in a sport where the risk of serious injury on any given play is part of the business, Sunday delivered a pair of franchise-altering, league-shifting knee injuries.
As he was attempting to drive the Chiefs into range for what could have been a season-saving field goal against the Chargers, Patrick Mahomes tore his ACL, bringing an end to the most frustrating season of the two-time MVP quarterback's career. Hours later, in the middle of a wildly entertaining game with the Broncos, Packers edge rusher Micah Parsons is believed to have suffered the same injury while attempting to chase down quarterback Bo Nix.
