Boxing News : Boxing star Claressa Shields wins first MMA fight at PFL 4

From the squared circle to the cage, Claressa Shields simply can't lose. Shields made short work in her MMA debut of Brittney Elkin, and the two-time boxing gold medalist proved she might have a future in the sport with a TKO win on Thursday night in the main event of a Professional Fighters League card. A two-time Olympic gold winner, Shields proved in her 155-pound fight she’s just as adept at unleashing a beating in mixed martial arts. She shook off a slow first two rounds before she got Elkin on the ground and needed a few heavy shots to cause the decisive damage. She earned the win with a right hand from the top at 1:44 of the third round. Shields ditched some of the flamboyant costumes she’s worn in boxing (where she's 11-0) for straight red trunks and top. She still wore her hair in a blue ponytail to raise awareness to the clean water fight that’s gone on for years in her hometown of Flint, Michigan. She already won the light middleweight, middleweight and super middleweight crowns in her boxing career and become the fastest fighter in history - either male or female - to become a three-division world champion. Shields only started her MMA training in December at the Jackson Wink MMA Academy in Albuquerque, New Mexico. PFL CEO Peter Murray said Shields would fight one more time this year for PFL before a decision was made for 2022.
