Billy Joe Saunders will make his American debut on the undercard of the rematch between YouTube stars KSI and Logan Paul on 9 November.
The 30-year-old Briton became a two-weight world champion when he outclassed Shefast Isufi in May.
“It’s a great chance to get some new fans onboard,” Saunders said.
Saunders, whose opponent is yet to be announced, feels the fight is a “chance to put his name in bright lights” in America.
KSI and Logan Paul, who each have more than 20 million YouTube subscribers, shared a majority draw when they first fought at Manchester Arena in August 2018.
On the YouTube fight, Saunders added: “The KSI v Logan Paul rematch has really captured the imagination of the British and American public and it’s something that sells. Fair play to them both, it’s going to be a great show.”
