Shannon Courtenay has explained that her period was the reason why she missed weight for her fight with Jamie Mitchell as she has been stripped of her world bantamweight title.
The 28-year-old came in at 120.5lbs, which is 2.5lbs above the limit for bantamweight fights.
Her bout will still go ahead, and Mitchell could win the vacated title if she takes victory as the M&S Bank Arena in Liverpool on Saturday.
In a post on Instagram she revealed that an early start to her menstrual cycle was the reason behind her not making the weight for the fight.
