UFC 15: Collision Course was a mixed martial arts event held by the Ultimate Fighting Championship on October 17, 1997, in Bay St. Louis, Mississippi. The event was seen live on pay per view in the United States, and later released on home video.
UFC 15 was headlined by a Heavyweight Championship bout between Maurice Smith and Tank Abbott. Abbott was brought in as a last-minute replacement for Dan Severn, who could not fight because of an injured hand.
UFC 15 also featured a Superfight between Randy Couture and Vitor Belfort, a Heavyweight Tournament, and two alternate bouts. The show also marked the last event to feature Bruce Beck, who had been the main play-by-play announcer starting with UFC 4.
Collision Course marked a major change in the UFC's rules, with limitations set on permissible striking areas. Headbutts, groin strikes, strikes to the back of the neck & head, kicks to a downed opponent, small joint manipulation, pressure point strikes, and hair pulling all became officially illegal.
