FLORHAM PARK, N.J. -- Last week it was Antonio Cromartie. This week it will be Eric Decker -- a key New York Jets starter attempting to recover quickly from a sprained knee.

Decker was a spectator at the start of the Wednesday's practice, as was fellow wide receiver Chris Owusu (leg). Neither was expected to practice. The question is, will they be ready by Sunday to play the Philadelphia Eagles?

Decker, injured in the fourth quarter of Monday night's win over the Indianapolis Colts, is considered day-to-day, according to the Jets. Unlike Cromartie, who rallied and didn't miss a game, Decker is working with a short week -- only five days for rest and recovery. Cromartie had seven days; that's a significant difference.

Owusu appears unlikely to play, meaning Quincy Enunwa and, possibly, Jeremy Kerley could move up the depth chart. Don't forget, the Jets also have rookie Devin Smith, who seems likely to make his debut.

In other injury news, rookie linebacker Lorenzo Mauldin (concussion) was on the practice field for the first time since his scary injury in the opener.
