Jets linebacker C.J. Mosley is out for the team's Week 8 matchup with the Jaguars on Sunday, Adam Gase announced on Friday.
The news comes two days after the head coach said that team doctors would be taking a "deep dive" into what's been ailing the University of Alabama product.
Mosley had been out since Week 1 with a groin injury, but returned to the active roster for Monday night's loss to the Patriots. He didn't appear to be fully healthy, and went without a solo tackle for the first time in his NFL career before coming out of the game after the score got out of hand.
"Seemed like every time he was on the ground, he'd get up and he just didn't seem comfortable," Gase said of Mosley on Wednesday. "So I was glad they pulled him out when they did. I didn't know what was wrong with him because all indications going into the game was he felt really good, especially watching him practice.
"I saw him look like the guy before the Buffalo game and I don't know what changed there."
The Jets haven't said whether it's a lingering injury for Mosley or if he re-aggravated something against the Patriots, but the Jets could certainly use him sooner rather than later. He is one of five Jets linebackers who appeared on Thursday's injury report.

Gase said Friday that placing Mosley on injured reserve is not out of the question. At the start of training camp, the Jets had both Mosley and Avery Williamson penciled into starting inside linebacker roles. They lost Williamson to a torn ACL in the preseason, and now the rest of Mosley's season is very much a question mark, as well.
