Cyborg's Final Fight: MMA Legend to End Glittering Career Against Ketlen Viera

The Final Bell: Cyborg’s Glittering Career Set for Explosive End

The mixed martial arts world is bracing for an emotional farewell. Cris Cyborg, widely hailed as one of the greatest female fighters of all time, will step into the cage for the last time on 22 August in Tampa, Florida. The 40-year-old legend defends her PFL featherweight world title against fellow Brazilian Ketlen Viera in what promises to be a spectacular send-off.

For two decades, Cyborg has been a force of nature—a knockout artist who has dominated five different promotions and won world titles across the UFC, Bellator, Strikeforce, Invicta, and now the PFL. Her record of 29 wins in 32 fights, with 21 knockouts, speaks for itself. But this fight isn't just about stats; it's about legacy, pride, and a dramatic twist involving boxing queen Claressa Shields.

A Career Rivaled by Few

Cyborg's journey began in 2005, when women's MMA was still a niche sport. She quickly became its most fearsome ambassador. Her raw power, relentless pressure, and technical brilliance made her a nightmare for opponents. From crushing Gina Carano in 2009 to capturing the UFC featherweight title in 2017, Cyborg has been a pioneer. Yet her path has also been marked by controversy—most notably, her bitter rivalry with Amanda Nunes, which ended in a 2018 knockout loss. But Cyborg rebounded, stringing together nine straight wins, including her most recent victory over Sara Collins in December 2024 to claim the inaugural PFL belt.

Now, she says enough is enough. “I want to go out on top, defending my belt against a tough opponent like Ketlen,” Cyborg told reporters. “This is my final MMA fight—but I’m not ruling out boxing.”

The Drama Behind the Fight: Claressa Shields Turns Down $2 Million

What makes this matchup even more tantalizing is the backstory. Cyborg had been in negotiations for a historic boxing showdown with undisputed heavyweight champion Claressa Shields. The MMA icon reportedly offered Shields a staggering $2 million purse to fight her in a boxing match. But Shields declined, opting instead to drop down to middleweight to face Kaye Scott on 15 August.

“This was why I’m returning to MMA instead of boxing Claressa Shields,” Cyborg wrote on X (formerly Twitter). “Since Claressa Shields has turned down my $2,000,000 offer to fight the 5–1 Kaye Scott, I might as well return to MMA and defend my PFL belt.” The jab was classic Cyborg—unapologetic and direct.

Shields, the two-time Olympic gold medalist, has yet to respond publicly, but the rivalry has already captured headlines. Fans are left wondering what could have been—and whether a future boxing match between these two titans might still happen after Cyborg’s MMA retirement.

Ketlen Viera: The Perfect Farewell Foe

Standing across from Cyborg will be Ketlen Viera, a 34-year-old Brazilian who recently left the UFC after winning 10 of her 15 fights in the promotion. Viera is a durable, well-rounded fighter with a submission game that could test Cyborg’s takedown defense. But she’s also stepping into the lion’s den against a motivated legend determined to end her career with a bang.

Cyborg herself acknowledged the challenge: “Ketlen is tough, experienced, and hungry. I’m excited to share the cage with her. She will give me a great fight.” Indeed, Viera has everything to gain—a win over Cyborg would catapult her into superstar status. But Cyborg has never lost a title fight (save for the Nunes bout) and has finished 21 opponents by knockout.

Legacy Beyond the Cage

Cyborg’s impact extends far beyond her fight record. She has been a trailblazer for women in combat sports, breaking down barriers and proving that female fighters can headline major events. Her rivalry with Ronda Rousey—though they never fought—helped elevate the sport’s profile. Off the mat, she’s an advocate for animal rights and a devout Christian, often sharing her faith with fans.

As the fight date approaches, the MMA community is already planning tributes. Social media is flooded with highlights, old interviews, and heartfelt messages from fellow fighters. “She changed the game,” says UFC veteran Michael Bisping. “Without Cyborg, women’s MMA wouldn’t be where it is today.”

Also in the News: Paul Hughes Sidelined Until 2027

In a separate development, Irish lightweight Paul Hughes has revealed he will not return to action until early 2027 after undergoing a second surgery in four months. The 29-year-old—who fought for the PFL title against Usman Nurmagomedov twice last year, losing both—revealed on Instagram that his body “broke down” after a knee injury forced him out of a March fight in Belfast.

“The truth is my body broke down towards the end of last year. My mental strength pushed me to try to do the impossible. I got close, not a single regret,” Hughes wrote. He did not disclose the nature of the second surgery, but sources close to the fighter indicate it was to address lingering issues from his leg procedure earlier this year.

Hughes has a record of 14 wins in 17 fights, including seven knockouts. His two defeats both came at the hands of Nurmagomedov, a dominant champion. The hiatus is a setback but not a career-ender; Hughes is only 29 and has time to recover fully.

What’s Next for Cyborg?

While Cyborg has closed the door on MMA, she leaves it ajar for boxing. “I love boxing, and I’ve always wanted to test myself in the ring,” she said. A potential superfight with Claressa Shields remains a tantalizing possibility—if negotiations can be resurrected. “The offer is still there,” Cyborg teased. “I’m not going anywhere.”

For now, all eyes are on Tampa, where a legend will write her final chapter. Will Cyborg go out with a knockout, or will Viera spoil the party? One thing is certain: it will be a night to remember.
