New Zealand rugby star Sonny Bill Williams (27), and South African heavyweight Francois Botha (43) are set to meet in the ring in November.
South African boxer Francois Botha says he has agreed to face fellow veteran Evander Holyfield for the WBF heavyweight title.
Francois Botha will engage in arguably his toughest fight since his boxing comeback when he takes on German Timo Hoffmann.
