Clark has a rare blood condition that nearly caused him to die after his last game played in Denver in 2007. Clark was hospitalized in Denver when complications from sickle-cell trait prevented oxygen from flowing into his spleen. He later needed operations to remove his spleen and gall bladder, and the 205-pound Clark lost more than 30 pounds before he finally began feeling better more than two months later.Clark received medical clearance to play Monday night, however, the source said the Steelers decided it wasn't worth the risk. . .
