The Pittsburgh Penguins might not have reigning NHL MVP Evgeni Malkin for a couple of weeks because of an undisclosed upper-body injury. Considering the way the rest of the Penguins are playing, Malkin can take his time getting healthy. Sidney Crosby tied a career high with five assists, and Chris Kunitz posted his second hat trick of the season as the Penguins rocked the New York Islanders 6-1 on Sunday night for their fifth straight win.
