Cris Cyborg announces pro boxing debut on September 25

Women's MMA GOAT candidate will make her professional boxing debut vs. former world title contender Simone Silva in Curitiba, Brazil.

Cris Cyborg, the only Grand Slam Champion in mixed martial arts history, will look to add another belt to her storied career. She is scheduled to face former Brazilian national boxing champion and four-time world champion contender Simone Silva (17-21), in a professional boxing title bout for the Fight Music Show promotion. It will take place on Sunday, September 25, in Cyborg's hometown of Curitiba, Brazil. 

The event will take place inside the Arena Da Baixada soccer stadium, the same venue that played host to Cyborg's big-show debut at UFC 198. The fight, contested at a 140-pound catchweight vs. Leslie Smith, was won by Cyborg via TKO in Round 1 in front of a crowd of over 45,000 fans.

Cyborg, who has won championship belts in the Strikeforce, Invicta FC, UFC, and Bellator MMA promotions, has also competed professionally in submission grappling and muay Thai. However, this bout will be her first boxing experience, having had no amateur or pro boxing bouts on her resume. Cyborg, who received her professional boxing license from the California State Athletic Commission in 2017, will be facing a veteran of almost 40 professional bouts. 

Opponent Simone Silva, who became the Brazilian nation boxing champion in 2007, has been in the ring against some of boxing's top female champions, including Amanda Serrano, Tiara Brown, Shelly Vincent, Hyun Mi Choi and Maricela Cornejo. Silva has competed for the WBC, WBA, WBO, IBA and WBC world championships, and has almost 300 rounds of professional boxing experience to Cyborg's zero.

"Simone Silva is a former Brazilian national boxing champion who has boxed all over the world against some of the sport's best female world champions while representing Brazil on the global stage," Cyborg said. "She has fought for a world championship in boxing four different times during her career, and is a proven and durable veteran, who is going to be a real challenge for my first experience inside of the boxing ring. I am excited to challenge myself in a completely different sport and see where my potential in boxing measures."

Details of the Brazilian broadcast of the event have not been announced. Fans living outside of Brazil can purchase an online live stream of the event. Also on the card will be vale tudo legend Jose "Pele" Landi vs. Acelino "PoPo" Freitas, with a music performance from Brazilian Superstar Wesley Safadao.
