Martin told the Tampa Bay Times after the game that he did not suffer a concussion. Teams generally don't allow players to talk to reporters if there is any risk of a concussion, so it appears Martin escaped without an issue.
Martin suffered the injury after taking a knee to the helmet while in pass protection. He subsequently was examined on the sideline, then taken to the locker room.
Martin is one of the best running backs in football, but the Bucs have a very thin backfield behind him.
"I think Doug is going to be fine," Schiano said, according to the Tampa Bay Times. "He got hit in the head, but he cleared really quickly. I saw him at halftime and he was fine. He was going to play one more play."
