The rookies, quarterbacks and injured players had to check in with the team in Florham Park today, and the Jets made a few moves.

Notably, RB Joe McKnight failed his conditioning run and won't practice with the team until he passes it. He was placed on the active non-football injury list.

Knight had fitness issues at the Jets rookie minicamp as well. He sat drills out and was physically ill during the first practice.

QB Erik Ainge was placed on the reserve non-football list with an undisclosed illness, and won't count against the 80-man roster. After signing Mark Brunell Wednesday, the Jets would have gone into camp with five quarterbacks in Mark Sanchez, Kellen Clemens, Kevin O'Connell, Brunell and Ainge.

The team signed safety Emmanuel Cook, who was a UFA at training camp last year but was cut and spent last season on the Tampa Bay practice squad. The Jets also waived LB Ezra Butler.

Every player will have to report to the training facility on Sunday, and go from there to the dorms at SUNY Cortland where training camp officially starts on Monday.
