CINCINNATI -- The Cincinnati Bengals are temporarily without their top two quarterbacks.
Brandon Allen left Friday's preseason opener against the Arizona Cardinals with a concussion, the team announced.
Allen, the team's top back-up, has taken all the first-team reps throughout training camp with starter Joe Burrow recovering from an appendectomy. Allen played Cincinnati's opening offensive drive before he went to the locker room to be evaluated for a concussion.
Reserve quarterback Jake Browning took over in his place.
Allen has been the team's top back-up quarterback since 2020.
