Billy Joe Saunders will make his return to the ring on the KSI vs Logan Paul 2 undercard on November 9 to defend his world super middleweight title.
Eddie Hearn will promote the card, with sources telling The Independent that the Matchroom promoter is now on board to put together an undercard after the YouTube stars decided to turn professional.
The Brit will defend his WBO belt at the Staples Center in Los Angeles, home of the Los Angeles Lakers, having won the title in May against Shefat Isufi on points.
Saunders then decided to amicably split with long-time promoter Frank Warren, having struggled to earn fights against the biggest names in his division.
The 30-year-old appears set to earn those fights now after teaming up with Hearn, who also has WBA champion Callum Smith in his stable of fighters, as well as WBO world middleweight champion Demetrius Andrade.
The stage will bring huge exposure for Saunders in America as he begins a new spell under Hearn.
YouTube stars KSI and Paul will turn professional after their draw in 2018, which drew 1.2 million pay-per-view buys, at £7.50 or $10 each.
