The knee injury Daniel Carcillo suffered on Monday might prove to be serious. Carcillo hurt himself while hitting Edmonton's Tom Gilbert from behind. Carcillo has already been suspended indefinitely, but that might prove to be the lesser concern. "We're still talking about the options with him there," coach Joel Quenneville said. "He had some tests done [Tuesday] and we're still evaluating him." At this stage, Quenneville wasn't willing to rule out the possibility that Carcillo would need surgery.
