The Pittsburgh Steelers could be dealt another blow if their star safety can’t play. Ryan Clark sustained a second concussion within three weeks and could be in question for the Baltimore Ravens game this Sunday. He suffered the injury in an overtime victory Monday night over the Kansas City Chiefs. Ryan also sustained a concussion in the week 8 meeting against the Washington Redskins. Coach Mike Tomlin stated that Clark “appears to be fine” during his Tuesday press conference. Suffering two concussions within a three week period could warrant Clark to sit against the Ravens. He’ll have to go through NFL protocols for evaluation, and a decision would be made later in the week.
