TEMPE, Ariz. -- On the eve of their biggest game of the season to date, the Arizona Cardinals lost one of their most important defensive players.
Defensive end J.J. Watt will undergo what is likely to be season-ending shoulder surgery, sources told ESPN's Adam Schefter on Wednesday night. No date has been set for the surgery.
The Cardinals host the Green Bay Packers on Thursday night in a matchup for early control of the NFC. Arizona is 7-0, and Green Bay is 6-1, producing, perhaps, the best Thursday night game of the Super Bowl era.
