Arizona Cardinals quarterback Drew Stanton underwent arthroscopic surgery for an infection, according to a report from Ian Rapoport of the NFL Network.
Stanton is recovering but may not play again this season, the report says.
Before news of the procedure, it was believed Stanton could return for the playoffs. Over nine games (and eight starts) this season, Stanton has passed for 1,711 yards with seven touchdowns and five interceptions.
The Cardinals have already secured a spot in the playoffs and can clinch the NFC West division if they win and the Seattle Seahawks lose to the St. Louis Rams.
