1956-05-18 Sugar Ray Robinson w co 4 (15) Carl Bobo Olson, Wrigley Field, Los Angeles, California, USA - WORLD. Referee: Mushy Callahan. Proving his win over Olson (160) last time out was no fluke, the champion once again took the latter out, albeit it took a couple of rounds longer. The first three sessions saw little action although it was clearly noticeable that Robinson was setting the pace with accurate punches from both hands while Olson was trying to work inside. In the fourth, Olson started fast, taking the initiative for the first time, but following a clinch and having dropped his guard he was put down heavily and counted out on the 2.51 mark after a left-right to the jaw had almost lifted him into the air.
It took three months of hard negotiation before Robinson could be induced to meet Gene Fullmer, who had recently eliminated Rocky Castellani (w pts 10 on 4 January at The Arena, Cleveland, Ohio), Ralph Tiger Jones (w pts 10 on 20 April at the Public Hall, Cleveland, Ohio) and Charles Humez (w pts 10 on 25 May at Madison Square Garden, Manhattan, NYC, New York) to head The Ring magazine ratings. Fullmer also had wins over Garth Panter, Jackie LaBua, Peter Mueller, Paul Pender, Gil Turner (twice), Del Flanagan, Al Andrews and Moses Ward to his credit.
With contracts finally drawn up at the end of September Robinson had earlier said he would never fight for the International Boxing Club again due to their miserly purses, but a return clause and 47½% of the gate and 60% of TV revenue persuaded him to change his mind. Scheduled for 12 December in Madison Square Garden, a week or so before the fight was due Robinson pulled out suffering a heavy cold and the date was put back until 2 January.
