Antwan Barnes, the promising rookie pass rusher, was carted off the field toward the end of the afternoon practice.

Barnes was holding his ankle after getting injured in a lineman drill.

Team officials said there was no immediate update on Barnes' injury.

"Hopefully, it's not serious and he'll be back soon," defensive coordinator Rex Ryan said.
If Barnes is out for an extended period, that likely would increase Jarret Johnson's duties as a rush end.

MOVING ON UP: Ben Grubbs, the rookie first-round pick, spent his first practice working with the starting offense. Because Chris Chester (sprained foot) did not practice, Grubbs played right guard for the first-team offense. By the way Grubbs is progressing, one can only wonder whether Chester will give up this spot.

MOVING ON DOWN: Devard Darling, who is trying to secure one of the last spots on the roster, didn't help himself during team drills. As a fifth-year receiver, Darling should know the offense by now. But with the defense blitzing, Darling failed to run a "hot" route and instead blocked downfield. Kyle Boller's throw sailed to the spot where Darling should have been.
