Pittsburgh Steelers wide receiver Antonio Brown suffered a concussion in Saturday's win over the Cincinnati Bengals, according to head coach Mike Tomlin.

Brown left the game after taking a scary hit to the head from Bengals linebacker Vontaze Burfict on an incomplete pass in the final seconds. Burfict was flagged for hitting a defenseless receiver.

The receiver was walked to the sidelines by trainers, and entered the league's concussion protocol following the game, according to Aditi Kinkhabwala of NFL Network.
