Browns' Mike Ford: Enters concussion protocol

Ford has been ruled out for the rest of Sunday's game against the Steelers with a concussion, Kelsey Russo of the Browns' official site reports.

Ford was initially cleared to return to Sunday's game, but he has since been diagnosed with a brain injury and will not return for the second half. Ford will have to clear the league's five-step protocol in order to play in Week 15 against Kansas City on Dec. 15.
