New York Jets cornerback Darrelle Revis has been ruled out for Sunday's game against the Pittsburgh Steelers.

Revis is recovering from a mild concussion sustained in the fourth quarter of last Sunday's game against the Bills.

The four-time Pro Bowler returned to non-contact practice on Friday for the first time since suffering the concussion. Revis was not cleared for contact, according to Jets coach Rex Ryan.

Tight end Dustin Keller and linebacker Bryan Thomas have also been ruled out with hamstring injuries.
