The heavyweight rematch between Anthony Joshua and Dillian Whyte was canceled by the promoter Saturday after Whyte's random pre-fight drug test found "adverse analytical findings" in his sample.
The British boxers were scheduled to fight Aug. 12 in London, almost eight years after their first bout Dec. 12, 2015. Joshua beat Whyte by TKO in the seventh round.
Joshua, 33, last fought Jermaine Franklin in April and won by unanimous decision. While Joshua was victorious, his fight was by no means a strong indication of his ability in the ring. He lost his previous two fights against Oleksandr Usyk, who retained the IBF, WBA and WBO heavyweight titles.
