World champion boxer Claressa Shields officially kicked off her MMA career with a win, beating Brittney Elkin by third-round TKO to close out 2021 PFL 4 from Oceans Casino in Atlantic City, New Jersey. 


It wasn't always pretty, but Shields showcased her potential as a striker while finding some other areas of her game to work on. 


Shields got off to a slow start. After stalking Elkin in the early moments of the first round, she had her takedown defense tested early.
