The event also featured a Superfight between Dan Severn and Mark Coleman. The fight would unify the UFC Superfight Championship with the UFC tournament championship and determine the first ever UFC Heavyweight Champion. Mark Coleman was a late substitution for Don Frye, who had earned the rematch with Severn after winning the Ultimate Ultimate 1996, but was unable to participate in UFC 12 because of injuries he had suffered in that previous event. Frye never returned to the UFC. "Judgement Day" also featured two alternate bouts in case of tournament injury.
