Mary Spencer vs Mikaela Mayer: Weigh-In Results & Betting Odds

We officially have a women’s unified junior middleweight title fight, as the WBA champion Mary Spencer (10-2, 6 KOs) and her opponent Mikaela Mayer (21-2, 5 KOs) both came in under the division’s 154-pound weight limit.

Initially, this was supposed to be for Spencer’s WBA title, but with Cecilia Breakhus recently announcing her retirement and vacating her WBC and WBO titles, now there will be three belts on the line when Spencer and Mayer meet in Quebec, Canada. This fight is now even bigger as more is at stake. Who will come out victorious on Thursday night?
