The Jets have made the corresponding move now that the Joe Flacco trade is official:
Jets have released veteran safety Adrian Colbert, per source.— Adam Schefter (@AdamSchefter) October 26, 2021
Colbert did a reasonably good job filling in while the Jets had some injuries at the safety position until he suffered a concussion himself. He made four appearances with three starts and had 16 tackles with the Jets but Marcus Maye and Ashtyn Davis each played every snap on Sunday, so the Jets no longer need the cover, especially with Sharrod Neasman also back. Colbert could be added back to the practice squad.
There should be more roster moves this week with the Jets likely to put some players on injured reserve and add at least one, but probably more, linebacker to the roster.
