Denzel Bentley will fight WBO middleweight champion Janibek Alimkhanuly on 12 November in Las Vegas.
The two-time British champion is the first to challenge the unbeaten Kazakhstan fighter for the world title.
"It is a fight I can win. I said yes straight away," said Bentley, 27.
"Why not go out there and enjoy the theatrics of Las Vegas and come back with a world title?"
