Conor Benn saw off the challenge of American Peter Dobson in Las Vegas with a unanimous decision victory to keep his unbeaten record.
The 27-year-old from London, who is unable to fight in the UK due to failed drug tests, won his second straight fight in the US as he went 12 rounds for the first time in his career.
The judges scored the welterweight fight 119-109, 118-110 and 118-110 in Benn’s favour to extend his record to 23-0.
After the fight, Benn said he would fight anyone promoter Eddie Hearn puts in front of him.
His career was thrown into turmoil in October 2022 after he twice tested positive for the banned drug clomifene in the lead-up to a bout against Chris Eubank Jr that was called off in fight week.
His provisional suspension was lifted by the independent National Anti-Doping Panel, although the British Boxing Board of Control and UK Anti-Doping have lodged an appeal against that decision.
Hearn said on Friday that Benn must be allowed to fight again in Britain to fill the void left by Anthony Joshua and Tyson Fury.
