Allen was cut by the Bengals on Saturday, Tom Pelissero of NFL Network reports.
The Bengals also jettisoned Jacob Dolegala, leaving just Ryan Finley as the sole backup, though Pelissero hinted the team could make a move for one of the top backup QBs on the market thanks to its No. 1 waiver-wire claim. Considering Allen did register three starts last season it's almost guaranteed he'll at minimum make it on a team's practice squad, but it's unclear as to where he'll fall at the moment.
