Which professional ice hockey player was the first to compete in six different decades?

The milestone was reached in 1997 when Howe played professional hockey in a sixth decade. He was signed to a one-game contract by the Detroit Vipers of the International Hockey League and at age 69, made a return to the ice for one shift. In so doing, he became the only player in hockey history to compete in six different decades at the professional level, having played in the NHL, WHA and IHL from the 1940s to 1990s.

Gordon Howe (March 31, 1928 – June 10, 2016) was a Canadian professional ice hockey player. From 1946 to 1980, he played twenty-six seasons in the National Hockey League (NHL) and six seasons in the World Hockey Association (WHA); his first 25 seasons were spent with the Detroit Red Wings. Nicknamed "Mr. Hockey", Howe is considered the most complete player to ever play the game and one of the greatest ice hockey players of all time.

A 23-time NHL All-Star, he held many of the sport's career scoring records until they were broken in the 1980s by Wayne Gretzky, who himself has been a major champion of Howe's legacy. He continues to hold NHL records for most games and seasons played. In 2017, Howe was named one of the "100 Greatest NHL Players".
