Donegal's Jason Quigley will fight Shane Mosley Jnr for the NABO middleweight title at the Michelob Ultra Arena in Las Vegas on 29 May.
Quigley had been due to face Mosley Jnr on 13 February but the fight was cancelled due to the Irishman suffering from an unspecified illness.
Quigley (18-1, 14 KOs) will now face Mosley (17-3, 10 KOs) in just over a month, with the bout on the undercard of Devin Haney's WBC world lightweight title defence against Jorge Linares.
"I’m excited that this fight is happening," Quigley said. "It’s been in the works for a while now. I’m delighted to be getting back into the ring and I’m ready to rumble.
"This fight is a massive step for me. There is a lot of meaning to this one."
Quigley suffered a major setback in 2019 when he was beaten by Tureano Johnson. Afterwards he linked up up with former world middleweight champion Andy Lee, earning two stoppage wins since as part of an encouraging rebuild.
