Anthony Joshua will face Daniel Dubois in an all-British showdown for the IBF world heavyweight title at Wembley on 21 September after Oleksandr Usyk confirmed he was vacating the belt.
Dubois is the IBF's mandatory challenger, and it was announced on Wednesday that he will go up against Joshua.
Usyk, 37, became the first heavyweight to hold the IBF, WBO, WBA and WBC belts when he beat Tyson Fury on a split decision in Saudi Arabia last month.
"Anthony and Daniel, listen. I know the IBF title is important to you. It is my present to you on 21 September," Usyk said in a video posted on social media on Tuesday.

Britain's Lennox Lewis was the last man to unify the major heavyweight belts – three at the time – prior to Usyk, in 1999.
Two-time world champion Joshua, 34, has 28 victories and three losses during his career while Dubois, 28, has won 21 of his 23 fights.
