WBO 147-pound champion Mayer (22-2, 5 KOs) had been hoping to secure a long-awaited showdown with Ring Magazine queen Price, who currently holds the WBA, IBF and WBC belts too.

However, when those negotiations broke down after months of talks, Mayer decided to face a different Brit in Cameron. The pair are set to fight in a unification for Cameron’s WBO junior-middleweight belt and Mayer’s WBA and WBC straps on an MVP card in Birmingham on August 29.

The winner will be just one fight away from becoming the undisputed 154-pounds champion, with Oshae Jones (9-0-1, 3 KOs) the current holder of the IBF title. But when asked whether that would be her primary target, Mayer said her ambitions still lie at welterweight. “I think the bigger fight is undisputed at 147 against Lauren Price,” the 35-year-old told The Ring.

“Oshae Jones has the other belt at 154 and besides the fact we're good friends, I don't know if that fight would happen next.”

So determined to maintain her position in the welterweight division, Mayer even agreed for this clash with Cameron to take place at a contracted catchweight of 148 pounds.

“After this I'm going to have to go back down to 147 to defend that belt pretty soon or they're going to strip me,” she adds. “So I'm hoping to get it done next after Cameron.”

Both Mayer and Price insist they want to fight each other but so far the two sides have not reached an agreement. The American says that terms were agreed for a fight to take place last year only for Price to change her demands late in the negotiations. When asked exactly what is to blame for the breakdown in communication, Mayer laid the blame squarely with Price’s promoter. “I think it’s a Boxxer thing,” she says. “We had the fight set for July of last year it was going to be the last fight they had on Sky Sports the last fight Top Rank had on ESPN.  "It was like the last chance to get it done we agreed on the number and purse, we agreed on the location — it was supposed to be here in Vegas — then all of a sudden they call back and they say ‘oh no Lauren Price wants more money, she wants this, she wants that, she's not into it.’

“I think that Ben Shalom or whoever's negotiating this stuff for her isn't keeping her in the loop. You don't come to a whole agreement on a fight without going back to the fighter and asking how they feel about it.

“I think they negotiated an entire deal and then when they took it back to her she was like ‘uh no.’ That's just irresponsible and shows a lack of communication on their side.

“It kind of screwed us over because we lost the TV slot for that and then they tried to get me to go over to Cardiff for $200,000. But I'm not fighting for undisputed for $200,000, you're tripping. I don't know what you're getting paid but that's absolutely not freaking happening.

“But that being said, I still think it's possible. I don't know, maybe I need to have a talk with Lauren Price face to face because I don't know what she's being told.” As one of the stars of women’s boxing, Mayer says she has now entered her “cash out era." So, after more than 100 amateur bouts and nearly nine years as a professional, how long does she have left in the game? “Well I just signed a six-fight deal with MVP so I plan to finish that and then that’s it," she says.

“That's why I want to get the biggest fights possible. So I got the Chantelle Cameron fight, then if I can get Lauren Price and then, who knows, maybe I can get Claressa Shields.

“That would be three and then I could get Oshae Jones for undisputed at 154 pounds, shoot, maybe I'll be done in four.”
