Revis does drills, status uncertain

Darrelle Revis has participated in some individual and team drills during practice, an encouraging sign for the New York Jets' star cornerback who is recovering from a concussion.

Revis' status for the team's game at Pittsburgh on Sunday was still uncertain, but he did much more Friday during the half-hour of practice the media are allowed to watch than earlier in the week when he was mostly restricted to riding the stationary bike.

Revis was injured last Sunday against Buffalo when teammate Bart Scott accidentally kicked him in the head.

The status of tight end Dustin Keller was even more uncertain after he was not on the field during the early portion of practice. He didn't practice Thursday after feeling soreness in his ailing right hamstring after practicing Wednesday.
