Cooper caught his only target for nine yards in Friday's 17-0 preseason win over the Steelers.
Cooper's lone catch came on a pass from fellow rookie Cade Klubnik in the two-minute drill to end the first half, with the Jets' second-string offense in the game. The rookie first-round pick out of Indiana has yet to work his way ahead of slot receiver Isaiah Williams, while Garrett Wilson and Adonai Mitchell appear entrenched as the team's top two wide receivers until further notice. Cooper's likely to feature in next Friday's preseason finale against the Giants, even if the Jets rest their veteran starters.
