Giovani Bernard exited Saturday night's wild playoff loss with a concussion.
The Bengals running back was knocked out on a helmet-to-helmet hit by Pittsburgh Steelers linebacker Ryan Shazier after catching a pass late in the third quarter.
Bernard was quickly ruled out and is in concussion protocol.
Following the play, Bengals running back Jeremy Hill scuffled with several Steelers players on the field, leading to a fracas between the rivals.
The Bengals also lost cornerback Dre Kirkpatrick (quad) and safety Reggie Nelson (ankle) during the game.
