Edgar Berlanga and Richardson Hitchins have signed multi-fight deals with Zuffa Boxing.
Their debuts with the new promotional powerhouse are expected this summer.
Berlanga will return to the ring under the Zuffa Boxing banner to reclaim his position as a top contender in the super-middleweight division.
The 28-year-old from Brooklyn has amassed a strong resume over his 10 years in the professional ranks with his only two career defeats coming at the hands of pound-for-pound great Canelo Alvarez and unbeaten knockout artist Hamzah Sheeraz.
He started his pro career by knocking out his first 16 foes in the first round.
"Zuffa Boxing is changing the game," Berlanga said. "I'm here for the biggest fights on boxing's best platform. I'm here to put the super-middleweight division on notice. 'The Monster' is back!
"Thank you to Dana White, Nick Khan, and the entire Zuffa Boxing team for believing in my talent. I also want to thank my father, Edgar Berlanga Sr, and my manager, Keith Connolly, for always guiding me in the right direction, and this move is no different. This is going to be a special journey."
Hitchins joins Zuffa Boxing in the prime of his career as one of the world's best super-lightweights. Born and raised in Brooklyn, he captured his first world title in 2024 with a dominant victory over then-unbeaten Liam Paro in Puerto Rico.
Prior to turning pro, the 28-year-old represented his parents' homeland of Haiti in the 2016 Summer Olympics.
"This is a major step forward in my career," said Hitchins. "I'm very grateful for this opportunity, and I want to thank Dana White, Nick Khan, and my manager, Keith Connolly, for giving a kid from Brooklyn the opportunity to fight on the biggest stage against the world's best fighters.
"With Zuffa Boxing in my corner, I'm going to show the world that I am a pound-for-pound, generational fighter."
