Femke Hermans vs. Mary Spencer II

Mary Spencer (7-1, 5 KOs) sought redemption against Femke Hermans (16-4, 7 KOs) in their October 11, 2023 rematch at Montreal’s Casino de Montreal, a year after Hermans defeated her by unanimous decision for the IBO title. The stakes were higher this time, with the vacant IBF junior middleweight title also on the line after Natasha Jonas vacated the belt. Spencer, a decorated Canadian amateur, overhauled her training camp post-loss, hiring coach Samuel Décarie-Drolet to address technical gaps exposed in their first fight. Hermans, a former WBO champion, entered with momentum from two 2023 stoppage wins and confidence from her prior victory. Promoters framed it as a grudge match, with Spencer vowing to "lead the dance" in Hell’s territory—a nod to Hermans’ punishing style in their initial bout. The event, streamed on ESPN+, featured a stacked Eye of the Tiger card, including Erik Bazinyan’s co-main title defense.
