One day after recovering a botched kickoff, a key play that led to a Jets touchdown in Sunday's win over the Bills, backup S Emanuel Cook was waived by the Jets.

Rex Ryan declined to give a reason, saying, "Every decision we make is generally for the benefit of our football team. I'm not going to get into the specifics of what led us to make a decision." A cryptic answer, to be sure.

Sources said it stemmed from something that happened Monday during the team's workout, the usual day-after conditioning session. The details are sketchy, but it appears the strength-and-conditioning coach thought Cook was late for the workout when he was actually there. Some close to the team believe Cook was released because one of the higher-ups in the organization was watching the workout and felt he wasn't running hard.

No matter what happened, it's curious. Cook's ouster definitely stunned some players. By the end of the afternoon, his locker was cleaned out and he was on the waiver wire. Obviously, he's not a big name, but he appeared in eight of the 11 games, contributing mostly on special teams.

To replace Cook, the Jets plan to sign S Tracy Wilson from the practice squad, according to Ryan.

In other moves, the Jets released LB Eddie Jones from the practice squad and re-signed LB Ricky Sapp.
