According to radio host Tony Marinaro, hockey legend Guy Lafleur will undergo quadruple bypass surgery on his heart Thursday. Marinaro states Lafleur went to get his heart checked Wednesday, and his condition was serious enough that his surgery was scheduled for the next day.

Lefleur, now 68, is a five time Stanley Cup champion. His NHL career spanned 17 seasons, mostly with the Montreal Canadiens. He also played for the Quebec Nordiques and the New York Rangers. He finished his career with 560 goals and 1,353 points in 1,126.

Lafleur scored at least 50 goals in six consecutive seasons, starting in the 1974-75 season. He was inducted into the Hockey Hall of Fame in 1988.
