Cris Cyborg is switching sports…

The 37-year-old mixed martial artist’s next fight won’t be inside an MMA cage — it’ll be in a boxing ring against Simone de Silva.

Cyborg, one of the best women’s MMA fighters of all time, said on her “The Catchup” YouTube show Monday that was finalizing a contract for her professional boxing debut.

By Wednesday, that was done.

Cyborg shared on Instagram that she would be fighting de Silva at 154 pounds in the main event of a card on Sept. 25 in Cyborg’s hometown of Curitiba, Brazil.

“It’s one of my dreams,” the 37-year-old Cyborg, currently the Bellator women’s featherweight champion, said of boxing.

The fight will be an eight-round boxing match with two-minute rounds and contested with 8-ounce gloves.

Cyborg is currently a restricted free agent in an exclusive negotiating period with Bellator, and sources said Bellator president Scott Coker has given his support for this boxing match.

PFL had made public overtures about putting together a fight between Cyborg and the two-time Olympic judo gold medalist, with the implication that PFL could potentially sign Cyborg as a free agent.

Cyborg said she has not spoken with PFL at all at this point.

“No, we never have any talks with PFL,” Cyborg said. “We never talked about this fight. I know there’s a lot of talk on the internet about making this fight happens in different ways, but we’ve never had the talk about anything.”

Cyborg did not say she is disinterested in the Harrison matchup, but Cyborg has always been vocal about the positives of her relationship with Coker and Bellator, which she has touted as having the best women’s featherweight division in MMA.

Cyborg said on the show that if Cyborg vs. Harrison happens while she is still with

Bellator, that would be “great.”

“I’m open to the best fights for my fans,” Cyborg said.

Cyborg (26-2, 1 NC), whose real name is Cristiane Justino, is a former UFC, Strikeforce and Invicta FC women’s featherweight champion. She has four Bellator title defenses and has won six straight fights overall. Cyborg’s only loss since her pro debut in 2005 was to current UFC double champion Amanda Nunes in 2018.
