In the title bout held in Toronto, Canada's Arena Gardens on August 24, 1931, Godfrey prevailed by knocking out Harris at 1:35 in the second round.

Harris also fought former World Heavyweight Champ Primo Carnera in 1935, seven months after Carnera lost his world title to Max Baer. In São Paulo, Brazil, Harris lost to the ex-champion in what ended up as his last fight.
