See main article: Ice hockey at the 1920 Summer Olympics. The 1920 Summer Olympics ice hockey rosters consisted of 60 players on 7 national ice hockey teams.[1] Played at the Olympic Games for the first time, and later regarded by the International Ice Hockey Federation (IIHF) as the first World Championship. Teams were required to be strictly amateur, so players from the Canadian-based National Hockey League (NHL) or other professional leagues were excluded. Canada sent the Winnipeg Falcons, who had won the 1920 Allan Cup, the amateur championship in Canada.
The matches were played 7 per side with 3 forwards, 2 defencemen, a rover, and a goaltender with no substitutions during the match.[2] Due to the tournaments format that saw some teams only play a single match several teams brought players that would never see the ice.
