In Boston Garden on December 12, 1933, Shore ended the career of Toronto Maple Leafs star Ace Bailey when he hit Bailey from behind. When Bailey's head hit the ice, he was knocked unconscious and went into convulsions. Moments earlier, Maple Leafs teammate King Clancy upended Shore with a hard check as he rushed up the ice. Angry, dazed, and thinking he was going after Clancy, Shore rushed at Bailey intent on revenge. In retaliation, the Leafs tough-guy Red Horner punched Shore, whose head hit the ice as he fell from the blow. Shore was knocked unconscious and required seven stitches but was not seriously injured. Bailey was rushed to hospital in critical condition with a fractured skull and was operated on for more than four hours. There were many fears that he could possibly die. He came out of a coma for the second time 10 days later, making a full recovery, but he did not play professionally again. When he was assured that Bailey would survive, league president Frank Calder suspended Shore for 16 games. An all-star benefit game was held at Maple Leaf Gardens on February 14, 1934, which raised $20,909 for Bailey and his family. Bailey and Shore shook hands and embraced at centre ice before the game began. Thirteen years later, the NHL introduced an annual all-star game.
