The Philadelphia Flyers will provide an update on Chris Pronger's condition Thursday. He visited with concussion experts, at the University of Pittsburgh Medical Center, Wednesday and the Flyers will have more information on what happens next for their captain after consulting again with their doctors. Pronger has been sidelined indefinitely since Nov. 19 after his concussion-like symptoms worsened. He had been experiencing headaches, nausea and fatigue, but played through them against Winnipeg before being removed from active duty.
