The fight for the IBF, WBA, WBO and WBC "franchise" lightweight belts has been postponed several times, with boxers waiting for a fight date since February, when a promoter tender took place. At this point, a date in November seems final.
For Lopez, it will be his first appearance in the ring since last year's duel with Vasyl Lomachenko. Kambosos earned the right to fight for the IBF title by defeating Lee Selby last year.
