New York Jets All-Pro cornerback Darrelle Revis is expected to miss the rest of the season with a torn anterior cruciate ligament in his left knee.
He will require surgery that should take about six months of recovery time.
Revis was injured in the third quarter of the Jets' 23-20 victory over the Miami Dolphins on Sunday while changing directions in pursuit of running back Daniel Thomas. Revis walked off the field under his own power, but seemed to be in considerable pain. He was then carted to the locker room.
Jets coach Rex Ryan announced the injury during his weekly press conference Monday.
"Obviously that's a significant injury," Ryan said. "It's something that we're going to have to overcome as a football team. We understand that. For him, I feel bad about it. He's such a great player and a great teammate. We're going to lose that presence. With that, I don't know what else to say about it. That's the horrible thing that came out of the game. The good thing is obviously we found a way to win."
Ryan said he would talk to Revis before deciding on placing him on injured reserve. The team has seven players on the roster who've had ACL surgery, including cornerback Antonio Cromartie.
"I know the way Darrelle is -- as competitive as it gets -- he's going to come back strong," Ryan said. "So before we do anything, I want to talk to Darrelle."
Revis was replaced by Kyle Wilson, who was a first round draft pick in 2010. Wilson has struggled and was picked on by the Dolphins on Sunday.
Revis had missed the previous week recovering from a concussion he sustained in the season opener against the Buffalo Bills.
Losing Revis delivers a significant blow to the Jets defense.
