Two teams in the Canadian Football League lost players, returning from an all-star game, in the 1956 crash of Trans-Canada Air Lines Flight 810.
As a result of these accidents, some professional sports leagues have developed disaster recovery plans should such an incident befall one or more of their teams.
[1] Each league, however, has established procedures to decide whether an accident is of sufficient scale to activate contingency plans to help rebuild an affected team's roster, typically involving a special draft.
[citation needed] The National Basketball Association (NBA) contingency plan activates if five or more players on a team "die or are dismembered".
[1][3] A special "disaster draft" would be held in which other NBA teams could only protect five players,[3][4] so that quality sixth men would be available.
[1][3][4] The National Hockey League (NHL) contingency plan activates if five or more players[3][4] on a team "are killed or disabled".
[6] The Kontinental Hockey League (KHL) contingency plan was implemented after the 2011 Lokomotiv Yaroslavl plane crash that killed the team's entire traveling roster.
