Concussion to sideline Jets CB Darrelle Revis against Dolphins

FLORHAM PARK, N.J. -- The New York Jets ruled their best cornerback, Darrelle Revis, out Sunday against Miami due to a concussion.

Revis did not practice this week and has been sent home after treatment in the mornings. Revis suffered the head injury during the Jets' 24-17 loss at Houston.

"[Revis feels a] little better each day, but not good enough for physical activity," head coach Todd Bowles said. "The [concussion] protocol is the protocol, but we got to clear him and he's got to feel better. There is always concern when somebody gets a concussion. You just don't know how bad it affects them."

The Jets (5-5) are expecting to have starting center Nick Mangold, who went through a full practice and is listed as probable with a laceration in his right snapping hand.

Defensive end Sheldon Richardson, who missed last Sunday's game with a hamstring injury, also participated in a full practice and is ready to return on Sunday.

The Jets, who will also be without safety Dion Bailey (ankle) according to Bowles, will likely start cornerback Marcus Williams in place of Revis.

"Anytime you lose a guy like that, you lose a one-on-one matchup guy," Bowles said of Revis. "... I like [Williams'] poise. He is very patient out there. The moment is not too big for him, the ball finds him, very instinctive, very smart. [But Williams] and the rest of the defense can probably work on tackling and wrapping up [more]."

"We definitely feel like... every game from here on out is a must-win for us," Williams said. "We need this win very bad. We know we are still in it for the playoff hunt. It is going to start this Sunday. I feel every game from here on out is a must-win."
