Boxxer are ready to up their offer to Mikaela Mayer for the long-awaited undisputed clash with Ring Magazine champion Lauren Price.

Mayer currently holds the WBO welterweight title which is the only alphabet belt missing from Price's collection.

The Welsh star has been out of action since March, when she claimed Natasha Jonas' WBC and IBF titles, having beaten Jessica McCaskill for the WBA belt in May 2024.

Her promoters Boxxer have had ongoing communication with Mayer's team but have so far failed to produce an offer the 35-year-old, currently ranked at No. 1 by The Ring, has deemed acceptable. Instead, she moved up to 154-pounds in October and became the unified champion by widely outpointing Mary Spencer in Montreal.

On Tuesday, she officially relinquished the WBO junior middleweight crown - with the sanctioning body president Gustavo Olivieri informing media outlets of her desire to 'pursue undisputed status' at 147-pounds, the American's more natural weight class.

She took to Twitter the following day, saying:

"Unfortunately we just learned that the three-belt champion needs a tune-up fight. I of course plan to stay busy in the meantime, so the team is working on what's next."

Meanwhile, Boxxer head Ben Shalom says he has not been dissuaded by the multitude of rejected offers and is confident of finding the financial offer that works for Mayer.

He told The Ring: "At the moment, it's not been accepted, but multiple offers have gone across. We've made repeated offers, not had one accepted yet. But I think it's getting close.

"Both fighters definitely want the fight. So I expect that to happen. She wants more money, it's as simple as that."

It had been suggested that Mayer was unhappy about the prospect of travelling to Cardiff, Wales to face Price, thus giving the unified champion home advantage. Shalom admits it will end up costing them more money but does not expect it to be a deal breaker.

He added: "I think money talks again but it probably adds a premium to the fact that we want it in Cardiff.

"So it's about offering more money but I don't think we're far off now. To be honest, I don't think there's any other fight that makes sense for Mikaela out there.

"It’s an opportunity to win the Ring Magazine belt and the three other belts. It's a huge fight so I genuinely think it's a fight that she wants. The promoters want as much money as possible for her to come over to Cardiff and that's it. But we will get there."

That fight however, is unlikely to take place before June and Shalom is planning to stage a headline show for Price sooner than that.

"She's fighting very soon and the date will be announced next week," Shalom said of Price.

"She'll fight in Cardiff, whether Mikaela or not. Maybe Mikaela will be in June but Lauren is fighting regardless.

"She's headlining in Cardiff. She's had a couple of issues not to do with us, as to what's kept out of the ring a little bit. But for me, she's the best female we have in this country, if not the world. She's going to headline in Cardiff on the BBC, and we'll announce and I'll be delighted to see her back. She's got huge fights ahead of her."
