"I'm training a lot in boxing now. I was thinking about maybe I do my next fight in boxing," Cyborg told TMZ Sports. "...Me and Cecilia Braekhus always talk back and forth. But, you know, I'm training.
"I think everyone is gonna be a very good match for me. It's gonna be a great fight. I like to challenge myself. I never look for the easy way. I like to train hard, and make the best fight for my career, for my fans."
Cyborg has a 22-2 (1) record in mixed martial arts but has not competed professionally in boxing.
Braekhus is one of the biggest names in women's boxing, sporting a 36-0 record heading into her April 17 bout against Jessica McCaskill.
"I always compete in everything, jiu-jitsu, wrestling, MMA, jiu-jitsu, grappling," Cyborg said. "But I never got the opportunity [to fight] Muay Thai, I never got the opportunity to fight box. For me, it's gonna be an honor to fight her."
Cyborg would join Conor McGregor among MMA's most notable faces who have stepped away from the sport for a boxing payday. McGregor lost to Floyd Mayweather via TKO in an August 2017 prizefight.
Cyborg last competed in MMA in January, defeating Julia Budd at Bellator 238.
