Mikaela Mayer didn’t care who was standing in the opposite corner on fight night.

All she cared about was that a fight night was still on her itinerary.

The former unified junior lightweight champion made due with an undesirable situation as she pushed forward with her ESPN+/BT Sport co-feature. A spirited challenge was offered by Sweden’s Lucy Wildheart, a very late replacement opponent whom Mayer soundly outpointed over ten rounds this past Saturday at Copper Box Arena in Hackney Wick, London.

“I wasn’t about to come to London and leave without a fight again,” Mayer noted in a post-fight locker room interview. “It happened the last time I was here. Unfortunately, the queen passed. We had to come back and do it all over again.”

It was nearly déjà vu for Mayer (18-1, 5KOs), who learned the morning of the pre-fight weigh-in that Christina Linardatou, a former two-time WBO 140-pound titlist was denied a license by the British Boxing Board of Control (BBBofC) and thus unavailable to fight. Mayer and her team was forced to scramble for a new opponent for her scheduled interim WBC lightweight title fight.

Top Rank secured the services of Wildheart (10-2, 5KOs), who is based in Brentwood, Essex and trained with Linardatou for this camp.

It was a more favorable scenario than when Mayer was sent home last September and dealt a five-week delay for her unification bout with heated rival Alycia Baumgardner (14-1, 7KOs). The sudden passing of Queen Elizabeth II occurred during fight week of their eventually scrapped event, for which both boxers were in peak physical condition and embraced the UK media before learning of the postponement.

Mayer eventually faced Baumgardner last October 15, where she dropped a hotly contested ten-round decision at The O2 in London. Her return to jolly old England came exactly six months later, where she avoided a pre-fight scare of being left without a fight and proceeded to secure her first win as a full-fledged lightweight.

“Definitely happy,” stated Mayer, who won by scores of 100-90, 98-92 and 99-91. “I needed this win, mentally for my career. Boxing is a very unforgiving sport. Two losses back-to-back could have been devastating. I was confident coming into this fight. I’m in my prime and I’m boxing great.

“I feel like it was a great fight. Thank you to my durable opponent, last minute stand-in. Really appreciative of her team stepping up. Onto the next one.”
