1986-09-06 Michael Spinks w rsc 4 (15) Steffen Tangstad, Hilton Hotel, Las Vegas, Nevada, USA - IBF. Referee: Richard Steele. Despite being the European champion Tangstad (214¾) was no match for Spinks (201), who had worked out his weaknesses by the second round before sending him to his knees with a right to the head in the third. The end was now in sight. Coming out strongly in the fourth Spinks quickly got down to business, putting Tangstad down twice more with big left hooks, and after the Norwegian got up from the second knockdown looking shaken and cut over the right eye the referee called the fight off on the 58 second mark.
Spinks forfeited his IBF version of the title in February 1987 when refusing to defend against Tony Tucker and signing to meet Gerry Cooney instead. Billed as ‘The Peoples’ World Heavyweight Championship’, but not supported by any of the commissions, Spinks stopped Cooney in the fifth round at the Convention Centre, Atlantic City, New Jersey on 15 June 1987. He then remained inactive until taking on Mike Tyson for the undisputed title.
