Not to be a harbinger of doom, but that injury kind of reminded me of Chris Webber's injury in the 2003 Western semis. It didn't really look bad, but all of a sudden he pulled up lame. Then he tried to come back on it, but couldn't and eventually got shut down and needed microfracture surgery (and was never the same). Obviously I hope it's just a strain, but that's what it reminded me of.
