1980-11-25 Carlos De Leon w pts l5 Marvin Camel, The Superdome, New Orleans, Louisiana, USA - WBC. Referee: Carlos Padilla. Scorecards: 145-142, 145-141, 145-145. Although the challenger made the better start, by the fourth round Camel (182) was scoring well with the southpaw jab and solid left crosses. Carrying cuts around the eyes from early on and being chased down by the stocky De Leon (182½) made life difficult for Camel. To De Leon's credit he never stopped throwing punches even if many of them were wayward. By the ninth it had become a war of attrition, but after De Leon had battered Camel all over in the 11th he made sure of victory in the eyes of two of the judges when putting in a grandstand finish.
Inactive for over a year, when a defence for De Leon against Tony Mundine in August 1981 failed to materialise the WBC set up an eliminator between Camel and Bash Ali which was won on points over 12 rounds by the former champion at the Cow Palace, San Francisco, California on 2 October 1981.
Meanwhile, De Leon began preparations for the fight by winning a non-title warm-up contest in mid-December. With the WBA also finally recognising the need for a weight class between the light heavyweight and heavyweight divisions they announced that Ossie Ocasio and Robbie Williams would meet to decide their first ever championship fight at the weight.
