FLORHAM PARK, N.J. -- Joe McKnight was on the Jets' practice field in a green No. 25 jersey, indicating that he really is moving to defense. He practiced with his new group, the defensive backs, after coach Rex Ryan confirmed the Jets were going to convert him into a cornerback in the wake of a season-ending injury to Pro Bowl corner Darrelle Revis.

Also notable was a new running back, Jonathan Grimes, wearing the while No. 21 most recently belonging to LaDainian Tomlinson.

As far as injuries, Stephen Hill (hamstring) and Bart Scott (toe) were the only two Jets who did not practice with the team. Both worked out on the bikes.

TE Dustin Keller (hamstring), LB Bryan Thomas (hamstring), WR Patrick Turner (hamstring), FB John Conner (knee) and S Eric Smith (hip/knee) were limited.

A whole raft of Jets will show up on the injury report but practiced fully: DT Sione Po'uha (lower back), QB Mark Sanchez (lower back), CB Antonio Cromartie (shoulder), LB Nick Bellore (shoulder), DE Mike DeVito (calf), OL Brandon Moore (hip), LaRon Landry (heel), Isaiah Trufant (ankle), Nick Mangold (wrist), CB Ellis Lankster (lower back) and Calvin Pace (Achilles).
