Buffalo Bills pass-rusher Von Miller is out for the remainder of the season after having surgery for an ACL injury, according to head coach Sean McDermott.

Miller underwent exploratory surgery in Texas on Tuesday and an ACL injury was found in his right knee. The pass-rusher was placed on injured reserve last Thursday before the game against the New England Patriots. The hope was that he would return this season. Miller said on his podcast last week that he hoped to return before this Sunday’s game against the New York Jets.

The Bills (9-3) currently have the top seed in the AFC with three games to come against the AFC East.

The Super Bowl 50 MVP suffered the injury on Thanksgiving at the end of the first half of the win against the Detroit Lions. Miller, who signed with the Bills in the offseason on a six-year, $120 million contract, started every game this season except Thursday’s and leads the team with eight sacks and 38 pressures.
