A specific venue and date is however yet to be confirmed for the all-British bout, which will see the winner become the undisputed heavyweight champion.
Joshua’s promoter, Eddie Hearn suggested it could take place on either 7 August or 14 August.
He added they were working with the same people as they did for Joshua’s rematch against Andy Ruiz Junior.
Joshua won back the WBA, WBO and IBF belts by beating Ruiz in Diriyah, on the outskirts of the Saudi capital Riyadh, in December 2019 after he had lost the titles in a shock defeat in June that year.
