Former IBF world super-middleweight champion Savannah Marshall was beaten on a split decision by WBO champ Shadasia Green in New York, earlier this month, on July 11.
It was just the second defeat of 34-year-old Marshall's professional career, having previously been beaten by her biggest rival Claressa Shields in their 2022 grudge match in London.
Flint's Shields became an undisputed middleweight champion by outpointing Marshall unanimously in the first-ever all-female fight card in the UK.
The build-up to the unification clash was intense and fiery due to the pair's genuine dislike of each other and bad blood after Marshall became the only ever fighter to inflict a loss on the American's record in the amateurs.
England's Marshall has been pursuing a rematch with Shields ever since, but that dream fight could now have suffered a further setback after her most recent defeat.
"The Silent Assassin" accepts that her conqueror Green will now have a stronger claim to the next fight with Shields, but claims it wouldn't be as big.
"My fight with Claressa is 10 times as big as Claressa versus Shadasia Green," Marshall told BBC Radio.
"I just want that Claressa rematch. I really do."
Marshall has the option of another rematch, however a contract issue may prevent any chances of that happening too.
Marshall admits she was "so confident" she would win against Green that there were no rematch clauses added into the fight contract.
"There's two fights out there for me at the minute," she added. "There's the rematch with Shadasia and I think that the Claressa rematch is still there.
"I've waited two and a half years, coming up on three years, for that rematch.
"Now I've lost my world titles and I've been beaten, it's probably less likely to happen. But I do think it's still an option, especially with the Netflix platform."
Despite suffering another setback against Green, the Brit will still power on through with her boxing career, stating, "I remember my first amateur coach saying to me 'You will wake up one day and you just won't want to do it any more'.
"But this is the train I'm on at the minute. It hasn't stopped yet."
