He played for the New York Islanders, Montreal Canadiens, Vancouver Canucks, Chicago Blackhawks, Hartford Whalers, Phoenix Coyotes, Toronto Maple Leafs and Dallas Stars. He is part of hockey lore as the man who ended the career of Islanders legend and teammate Bob Nystrom with an accidental high stick that almost cost Nystrom his eye.
