The 1933/34 NHL season was the 17th season in the National Hockey League . Nine teams played 48 games each. The Stanley Cup won the Chicago Black Hawks after a 3-1 win in the final series against the Detroit Red Wings . After the jubilee celebration in Chicago, the Hawks had only reason to be sad during the summer break. With goalkeeper Charlie Gardiner and rookie Jack Leswick, two Hawks players died after the end of the season. Another player was able to read his obituary in December. In a tough game between the Bruins and Maple Leafs, Eddie Shore was the first to be the victim of a tough attack by Toronto's King Clancy . When he became the perpetrator, Ace Bailey was mistakenly the target of his attack. Bailey was checked from behind and hit his head on the ice. He suffered severe concussions in the process. His life was saved in a nearby hospital, but he never returned to the ice as a player. The day after the game, his obituary was posted in a Boston newspaper. Shore was banned for 16 games. In order to support the invalid Bailey, a team with the "sinner" Eddie Shore competed in the first All-Star Game on February 14th in Toronto . The proceeds of $ 20,900 went to King Clancy. On February 22, 1934, a shirt number was blocked for the first time in ice hockey. The honored was Lionel Hitchman of the Boston Bruins , whose jersey number 3 was never awarded again.
