"Goaltender Olie Kolzig went down with what appeared to be a groin injury during today's practice at Kettler Capitals Iceplex. The extent of the injury was not immediately known. But I can safely say that it didn't look good.
"The veteran screamed as he slid from side to side while trying to stop a 2 on 1 early in the session. He stayed down for about a minute as teammates and training staff came to his side. He eventually skated off on his own, but was clearly hurt."
UPDATE: Preliminary reports have Olie out for at least three weeks with a knee injury. Perfect.
