The Jets placed Cooper (shoulder) on injured reserve Sunday with a designation to return, Al Iannazzone of Newsday reports.
Cooper suffered a shoulder injury during Friday's preseason finale against the Giants. The rookie sixth-rounder is set to be a primary piece of depth for the Jets' offensive line throughout 2026. Cooper will be required to miss at least the first four games of the regular season until he is eligible to return to the Jets' active roster.
