Blackhawks chairman Rocky Wirtz admitted on Friday that the team didn't give Marian Hossa a physical before they signed him. Hossa had shoulder surgery on Friday that will cause him to miss four months of action. "Dr. [Michael] Terry looked at the MRIs before we signed," Wirtz said. "There was still a chance he didn't need an operation. It's a small tear, we knew that. We thought it was 50-50 he could play with it. We knew exactly what it was. It wasn't where it was questionable or it would be severe. Dr. Terry, one of his specialties is shoulders, and he said he'll miss 19 to 20 games. It could be longer, of course. You have to depend on his advice. That's what he's telling us."
