FLORHAM PARK, N.J. -- Is New York Jets general manager John Idzik feeling the heat? Normally, he pops out for a practice or so per week. But since taking criticism for a thin roster and adding pricey wide receiver Percy Harvin, Idzik has been on the sideline each day this week during the portion of practice open to the media.

On Friday, he spent that time alongside coach Rex Ryan, no doubt watching Harvin during the walk-through. Harvin had a few nice catches during the session.

The Jets had all players on the field for the second straight day, including linebacker Trevor Reilly (knee) and wide receiver Greg Salas (wrist, ankle), who Ryan said were unlikely to play Sunday against the Bills because of their injuries.

A few players spent time with trainers before joining their position groups, including offensive lineman Willie Colon (knee), wide receiver Eric Decker (hamstring) and running back Chris Johnson (ankle). Tight end Jeff Cumberland, running back Chris Ivory and linebacker Jason Babin also spent some time with the trainers, although they weren't listed on the injury report Thursday.

Reilly has shaved his head hoping it would break the Jets' six-game losing streak. It's something of a superstition he has had going back to his college days at Utah, he said.

If the Jets win, he'll look dedicated. In the meantime, he looks ... bald.
