British Nigerian-born boxer and Anthony Joshua is to have a re-fight with the man he recently defeated in an epic boxing bout at the Wembley Stadium, London in May 2017.
The reverse bout has been fixed for October.
The newly crowned IBF and WBA heavyweight champion is to fight the former holder of the double titles, Wladimir Klitschko.
The fight was witnessed by a post-war record crowd of 90,000.
The rematch was to have taken place at the Principality Stadium in Cardiff because of the retractable roof.
But, promoter Eddie Hearn has ear-marked October 28 as the most viable date for a fight in the Welsh capital.
But Hearn is also exploring the option of staging the fight overseas, which would make the 28 October date more flexible.
