Claressa Shields is setting her sights on the heavyweight division – for now.

After a dominant debut in July where she stopped Vanessa Lepage-Joanisse in just two rounds to claim the WBC and WBO titles, the four-division world champion Shields (15-0, 3 KOs) is ready for her next challenge Sunday when she takes on undefeated challenger Danielle Perkins (5-0, 2 KOs).

The bout will headline a Salita Promotions card on DAZN that is dubbed “Super Brawl Sunday” at the Dort Financial Center in Flint, Michigan, marking a hometown return for Shields.

“To be honest with you, it's hard to get fights with the girls that are smaller now,” Shields told The Ring. “I moved up two weight classes to fight at heavyweight. I am a natural 160/168 pounder. And I fought at 154. Sadly, these girls talk a lot but don't sign the contract to fight at 154, 160, 168. I'm stuck at heavyweight because these girls will actually fight me and they are more of a challenge. I'm going to help build the heavyweight division in women's boxing and show what a heavy hitter really is, just like I did in my last fight.”

At 29, “T-Rex” Shields, the two-time U.S. Olympic gold medalist isn’t just making waves in the ring; she’s also stepping into the spotlight on the big screen. Her biopic, The Fire Inside, starring Ryan Destiny, premiered on December 25, offering an in-depth look at her life and career.

Looking to play spoiler on the Hollywood script is the 42-year-old Perkins, a former college basketball player at St. John’s University and a professional baller in Europe who transitioned to boxing after a life-altering accident in which she was struck by a car. Perkins rebounded in a big way, however, winning the 2019 IBA Women’s World Championships before turning pro in 2020.

Most recently, Perkins secured a six-round unanimous decision victory over Christianne Fahey on the Shields-Lepage-Joanisse undercard.

Perkins’ credentials have caught Shields’ attention.

“I believe Danielle Perkins is a force to be reckoned with,” said Shields. “She's very athletic and has an amateur background with world championships. She is going to be a great challenge. She's not someone that I’m overlooking. It's not an easy fight for me. I feel that I’m the greatest woman of all time. But she's going to come in the ring 195-200 pounds on fight night. I have to really lock in. I’ve never been that big. I won't be that big on fight night. I have to use everything that I have to come out on top. Who wants to have a movie come out about their life across the nation and then come out and not perform and win? There's a lot of pressure, actually.”
