The promotional company announced Friday that former WBO champ Chris Billam-Smith (22-2, 14 KOs) and Chev Clarke (12-2, 9 KOs) will square off in the 12-round main event of Zuffa Boxing 12 on November 7 at Copper Box Arena in London. Paramount+ will stream the show in the United States and Canada and Sky Sports will televise it in the United Kingdom and Ireland.

British light heavyweight contender Zach Parker (26-2, 18 KOs) will also square off against Russian southpaw Umar Dzambekov (14-0, 10 KOs) in a 10-rounder on the undercard November 7. The action will include another cruiserweight Zuffa signed recently, England’s Lucas Roehrig (9-0, 5 KOs), against Scotland’s Connal McDonald (5-1, 1 KO) in an eight-round bout as well.

Scottish middleweight Sam Hickey (6-0, 3 KOs) and American heavyweight Da’Mazion Vanhouter (13-0, 10 KOs) are among the prospects scheduled to compete that night against opponents to be determined.

Billam-Smith and Clarke are amateur rivals who won on the same Zuffa card June 6 in Billam-Smith’s hometown of Bournemouth, England.

Billam-Smith stopped Canadian contender Ryan Rozicki (21-2-1, 20 KOs) after the seventh round of an action-packed main event that night. Clarke came back from two fourth-round knockdowns to drop and stop England’s Jack Massey (23-4, 13 KOs) in the seventh round of the co-feature.

Clarke, who competed at the Summer Olympics in Tokyo four years ago, went 2-0 against Billam-Smith in amateur matches.
