Jets DE Muhammad Wilkerson returns to practice field

FLORHAM PARK, N.J. -- After missing two games with turf toe, defensive end Muhammad Wilkerson returned to the practice field Wednesday as the New York Jets began preparations for the Tennessee Titans. How much he practiced -- or if he practiced -- wasn't immediately clear, but it was a positive step.

Tight end Jace Amaro, sidelined the last two games with a concussion, also made an appearance, wearing the red, no-contact jersey, as required by the NFL's concussion protocol. On Monday, coach Rex Ryan seemed encouraged about Amaro's chances of playing this week. Wilkerson's status appears less certain.

As expected, wide receiver Percy Harvin (sprained ankle) wasn't seen at practice. He's unlikely to play this week. In other injury-related developments, safety Antonio Allen (broken hand) sat out positional drills. Linebacker Trevor Reilly (head) wore the red jersey.
