1983-11-25 : Larry Holmes 219 lbs beat Marvis Frazier 200 lbs by TKO at 2:57 in round 1 of 10
- This was a non-title fight, so far as the WBC and the Nevada State Athletic Commission were concerned. The WBC refused to sanction the fight. They wanted Holmes to defend against Greg Page, the #1 contender, but Holmes wanted more than the $2.5 million he was being offered by promoter Don King to fight Page. Holmes got $3.1 million to fight Frazier.
- The Holmes-Frazier fight was a mismatch. Holmes dropped Frazier with a right hand midway through the round. Frazier got up to one knee and then rose at the count of eight. Holmes backed Frazier into a corner and pummeled him with right hands until referee Mills Lane stepped in and stopped the fight.
- On December 11, 1983, Holmes relinquished the WBC title and accepted recognition as world champion from the newly-created International Boxing Federation.
- In October 1982, at the World Boxing Association annual convention, Bob Lee, president of the United States Boxing Association, lost in his bid to become WBA president against Gilberto Mendoza. Lee and others withdrew from the convention after the election and decided to organize a new world-level organization. The new group was first named the USBA International, but the name was soon changed to the International Boxing Federation.
