Heavyweight champion Anthony Joshua will put his four title belts on the line on September 25 after it was confirmed the British heavyweight will face Oleksandr Usyk at the Tottenham Hotspur Stadium.
Joshua, 31, currently holds the WBA, IBF, WBO and IBO titles and while he wanted to unify the division against Tyson Fury, he has been ordered to defend his WBO title against mandatory challenger Usyk.
'The date is set and we are fully locked in,' Joshua, who toured the stadium prior to Tuesday's announcement, said.
'I put it all on the line again and it's time to defend my crown.
