Wide receiver Dane Sanzenbacher was placed on injured reserve with a concussion and replaced on the Cincinnati Bengals’ playoff roster by wide receiver Cobi Hamilton.

Hamilton, in his first season, played in all four games in the preseason with the Bengals and caught eight passes for 127 yards and one touchdown. He spent three weeks of the regular season in September on the Philadelphia Eagles’ practice squad before moving to the Bengals squad practice squad prior to Game 6.

Sanzenbacher was diagnosed with a concussion Dec. 28 at Pittsburgh, when No. 1 wide receiver A.J. Green also entered the NFL’s concussion protocol.

Sanzenbacher, in his fourth season out of Ohio State, played in 10 games in 2014 with nine receptions for 105 yards.
