Penguins center Sidney Crosby fought with Stars defenseman Matt Niskanen on Wednesday night, just the fifth fight of his NHL career. "I never saw that coming," Niskanen said. "We were up 4-1 and he was probably trying to get the team going. He asked me to go and we went. "I didn't say a word to him all night. I wasn't on the ice with him all night. I made sure he really wanted it and we went. It happens."
