Anthony Joshua will face Jermaine Franklin to prepare for further bouts against orthodox fighters, with Eddie Hearn wanting him to move away from southpaws.
The Briton will face the American at The O2 in London on April 1 in his first fight since falling to a second consecutive defeat against Oleksandr Usyk.
The two-time world champion is looking to build his form back up after his pair of stinging losses against the Ukrainian, with the 29-year-old Franklin his first test.
In part, the latter has been chosen to offer a taste of orthodox fights for Joshua, with Hearn hoping for future bouts against Deontay Wilder, Dillian Whyte and Tyson Fury to follow.
"Really, it came down to the style," Hearn told Matchroom.
"I think AJ's coming off the back of two fights against a southpaw, the best southpaw in boxing, in Oleksandr Usyk, and wanted an orthodox fighter.
"The training team really sort of looked at it and said [that] if we're gonna go and fight [Deontay] Wilder, Dillian Whyte, Tyson Fury, there's no point in us going back and fighting a southpaw."

Franklin has 21 wins from 22 professional fights, with his only loss coming against Whyte in November last year.
Joshua had just one career loss before he faced off with Usyk originally in September 2021, losing his WBA (Super), IBF, WBO, and IBO titles in the process.
He then failed to claim revenge in the rematch in August in Jeddah, dropping him to a 24-3 professional record.
