Anthony Joshua said he would be ready to fight world champion Tyson Fury in December after he was issued a public challenge on Monday to fight a "Battle of Britain" for the WBC heavyweight boxing belt.
Joshua, 32, suffered a second straight loss to Ukraine's WBA, WBO, IBF and IBO champion Oleksandr Usyk in a title rematch in Saudi Arabia last month, and has said he wants to return to the ring before the end of the year.
Fury announced last April that he was fulfilling a promise to his wife to retire but has subsequently said he will fight again.
