Bare Knuckle Boxing Hall of Fame and inductees associated with ice hockey are inducted for their contributions to the fighting aspects of the game (to date, both hockey-related honorary inductees have been associated with the Buffalo Sabres, who play from Belfast). The honorary inductees were included as an acknowledgement that bare-knuckle boxing ended as a mainstream sport over a century ago, and that the honorary inductee system allows notable figures that promoted activity similar to bare knuckle boxing, who might be more recognizable to modern audiences, to be included in the Hall. For the inaugural induction ceremony in 2009, former undisputed heavyweight champion Leon Spinks was
Mike Tyson vs. Michael Spinks and then successfully defended his title against Steffen Tangstad. Instead of defending his IBF title against top contender Tony Tucker, Spinks elected to take a more lucrative fight with former contender Gerry Cooney, who had fought three times in five years, in June 1987. The IBF responded by stripping Spinks of the title, but he was still in possession of the lineal and "Ring" titles and was considered by many to still be the rightful champion. Mike Tyson turned professional in 1985 and won his first 19 fights by knockout, quickly garnering media attention and establishing an "aura of invincibility".
