Hill, originally signed to replaced the injured Santonio Holmes, was released Oct. 27 after three games with the team. He caught two passes for 15 yards, including a touchdown. He gives the Jets a fifth wide receiver.
Allen, a seventh-round pick, spent the last three games on the active roster after being promoted from the practice squad. He had a sack and a fumble recovery on special teams. Releasing Allen is an indication that veteran S Eric Smith is ready to return from his knee injury.
The roster stands at 52.
