Pittsburgh Steelers wide receiver Antonio Brown has left the Thursday night game against the Baltimore Ravens with an apparent head injury.
Brown took a hard hit following a big catch on third down during the Steelers first offensive drive.
The Steelers drive came to an end when wide receiver Justin Brown fumbled following a reception deep in Ravens territory.
The Steelers only dressed four wide receivers so Darrius Heyward-Bey will see more playing time with Antonio Brown sidelined.
Brown is being evaluated for a possible concussion. His return is questionable.
