New York Jets cornerback Darrelle Revis has fully participated in practice for the first time since suffering a concussion three weeks ago.

Revis is listed Friday as probable for the Jets' game against the Tennessee Titans on Sunday. Coach Todd Bowles says the cornerback still needs to clear one more neurological test before being able to play.

Revis has been in the NFL's concussion protocol since being injured Nov. 22 at Houston. Players need to clear a series of tests before they are fully cleared to participate in games.

Revis didn't wear a red no-contact jersey, as he did Thursday, when he said after practice that he expects to play.

Marcus Williams, Revis' backup, is questionable with a sprained knee. Linebacker Calvin Pace (abdomen) is probable.
