The Jets released Firsker on Tuesday, Ethan Greenberg of the team's official site reports.
The veteran tight end played in a career-low two regular-season games with Detroit last season, spending most of the campaign on the Lions' practice squad. It appears he may need to settle for another practice-squad role in 2024 in order to have a chance to make it back to an NFL roster. Firkser's best season came in 2020 with Tennessee, when he caught 39 passes for 387 yards and a touchdown over 16 regular-season contests.
