Graham (knee) has been ruled out for the remainder of Thursday's Week 4 matchup versus Pittsburgh, Chris Easterling of the Akron Beacon Journal reports.
Graham suffered a knee injury early in the first half and was ruled out shortly after halftime. The second-year pro didn't record any defensive statistics prior to his exit. Mike Hall suffered an ankle injury in the contest and is questionable to return, leaving Maliek Collins and Adin Huntington as Cleveland's only defensive tackles.
