Allen completed 17 of 34 pass attempts for 149 yards and two touchdowns across six appearances in 2021.
Allen also logged seven carries for minus-1 yards and committed one fumble. The bulk of his NFL action this season came Week 18 at Cleveland, a spot start in which Cincinnati lost 21-16 to close out the regular season. Now scheduled for free agency after the conclusion of the postseason, Allen may have to search for his next backup role elsewhere.
