After five seasons in Baltimore, the 27-year-old Mosley signed a five-year, $85 million free agent deal in March with the Jets that included $51 million guaranteed.
He was projected to be the quarterback of coordinator Gregg Williams’ defense, and he got off to a terrific start with his new team. Mosley had six tackles, returned an interception for a touchdown, recovered a fumble and had two passes defensed against the Bills — but hurt his groin while breaking up a play in the end zone near the end of the third quarter.
Mosley sat out four games before returning against New England on Oct. 21. He aggravated the injury during that game and acknowledged he wasn’t at full strength. Mosley had just three assisted tackles against the Patriots — the last game he’d play this year.
Despite Mosley’s absence, the Jets have played well overall on defense this season. New York is ranked No. 6 in the NFL in total yards allowed and No. 1 against the run.
Mosley is the 15th Jets player to end up on injured reserve, and the seventh starter — joining linebacker Avery Williamson, wide receiver Quincy Enunwa, cornerback Trumaine Johnson, center Ryan Kalil, guard Brian Winters and tight end Chris Herndon.
The Jets filled Mosley’s roster spot by claiming safety Bennett Jackson off waivers from the Ravens. It’s the second time New York has claimed Jackson, doing so in September when he was cut by Baltimore. The Jets waived him a few weeks later and re-signed him to the practice squad, but the Ravens signed him to their active roster in October.
