The New York Jets have a tough match coming up against the Oakland Raiders, and they will need all the help they can get to pull off an improbable upset. Unfortunately, C.J. Mosley isn't one of the men head coach Adam Gase can count on performing this Sunday.

The groin injury Mosley sustained is reported to be more serious than first thought, and it's highly likely that he'll finish the season from the sidelines as he recovers from his injury.

“Adam Gase spoke to media on Wednesday and was asked what Mosley's status is for the rest of the season,” Jets Wire's Spencer Aber writes. “Gase said he doesn’t really have an answer to that and that Mosley is going through the process of his rehab. The initial diagnosis was that Mosley would be out at least six weeks, but groin injuries are tricky.”

This isn't the first time the inside linebacker sustained this injury. He had this injury during Week 1 against the Buffalo Bills. He was out for the next five weeks but was able to make a recovery and play for the team against the New England Patriots, a one-sided defeat. He reinjured his groin and is now assessed to be out for the remainder of the season.

Mosley was an important linebacker for the Baltimore Ravens, and the Jets hoped for more of the same when he made the jump. Through his six-year career, he's notched a total of 606 tackles, 10 interceptions, six forced fumbles, and 8.5 sacks. Fans can only hope that he returns a lot stronger come the 2020 season.
