Ryan Clark practiced today with his teammates, but it remains unclear whether he will play for the Steelers in Denver next Monday night.
Coach Mike Tomlin said that determination will be made later in the week. He and Clark, his starting free safety, met with doctors last Thursday and "he's received medical clearance to play in this football game," Tomlin said.
"So now, the decision lies with he and myself. We're going to weigh all ouroptions and evaluate this thing as we proceed throughout the week."
Wide receiver Santonio Holmes also has sickle cell but he said he will play, and that he's never given it a second thought. He played in Denver in 2007 without any ill effects. Tomlin said Clark has another unnamed medical condtion besides his sickle cell that lead doctors to believe his case is "unique" and that many other players with sickle cell trait have played in Denver without any negative reaction.
