David John Semenko (July 12, 1957 – June 29, 2017) was a Canadian professional ice hockey player, coach, scout and colour commentator. During his National Hockey League (NHL) career, Semenko played for the Edmonton Oilers, Hartford Whalers and Toronto Maple Leafs as an enforcer. During his tenure with Edmonton, he notably protected Wayne Gretzky as an "on-ice bodyguard" during Gretzky's early career. Semenko won two Stanley Cups with the Oilers in 1984 and 1985. He was also the last player to score a goal in the World Hockey Association (WHA) before it folded and merged with the NHL.
