The Jets have waived/injured safety Antonio Allen and signed linebacker Freddie Bishop to their active roster, the team announced Saturday.
Allen (concussion) had been ruled out for Sunday's game against the 49ers in the team's final injury report on Friday afternoon. He had three total tackles in 12 games for the Jets this season, his fourth year with the team.
Bishop, one of the team's final cuts before Week 1, was re-added to the practice squad in early September. He has yet to take a snap in a regular-season game.
