Jets LB Lorenzo Mauldin likely needs season-ending back surgery due to a herniated disk, head coach Todd Bowles said on Thursday.
Mauldin is currently undergoing tests to see if surgery is necessary, Bowles said, according to Calvin Watkins of Newsday.
The 24-year-old Mauldin, the Jets' third-round pick in 2015, was placed on IR after originally making the 53-man roster, meaning the earliest he can return would be Week 9.
With the NFL's new IR rules, Mauldin was eliglble to be one of two players on IR who returns at some point this season.
Mauldin did not play in any of the Jets' four preseason games due to a back injury.
He had 16 combined tackles and 2 1/2 sacks in 11 games for the Jets last season.
