UFC flyweight Paige VanZant tweeted late Sunday night that she broke her right arm in a decision loss earlier in the evening to Jessica-Rose Clark in St. Louis.
The injury happened when VanZant (7-4) threw a spinning back fist in the second round of the three-round fight, which she finished.
VanZant's inability to throw or defend effectively with that arm from that point on seemingly played a factor in VanZant dropping her second consecutive fight and third of her past four.
Clark, an Australian who now fights out of Las Vegas, improved to 9-5. It was the second win of her UFC career, her most recent being a split decision victory against Bec Rawlings in November.
