Savannah Marshall ended her two-year boxing layoff with a narrow split-decision loss by Shadasia Green on the Katie Taylor-Amanda Serrano 3 undercard in New York, but has since ruled out retiring.

Instead, the 34-year-old insisted the fire burns within her to avenge her two career defeats.

The Hartlepool native, who spent nearly a decade in the amateur system before turning pro in 2017, lost her leverage and IBF world championship on a frustrating return stateside against one of MVP's first female signings in Green (16-1, 11 KOs).

Marshall had long pursued a rematch with amateur rival Shields, who has since moved up to and secured undisputed status at heavyweight since skilfully outpointing her in away territory during their October 2022 showdown on BOXXER's all-women's card in London.

Shields, who returns on DAZN this weekend against New Zealand's IBF light heavyweight champion Lani Daniels (11-2-2, 1 KO), has been vocal about wanting to test herself with fresh matchups across different divisions — provided the financials warranted the requisite sacrifices.

She had an eager eye on the Taylor-Serrano 3 bill, scouting potential foes, and came to the conclusion that none of those competing on the card would be remotely competitive against her.

Marshall thinks differently, though has work of her own to do now after losing a 10-round split decision and willingly opting for no contractual rematch clause.

In conversation with BBC Radio Tees, the former two-division world champion said: "My fight with Claressa is 10 times as big as Claressa versus Shadasia Green."

Green lost a wide 10-round decision to Franchon Crews-Dezurn for the then-vacant WBC super middleweight title in December 2023, and two fights later narrowly eked past Canada's 7-0 pro Melinda Watpool to win the WBO belt.

"I just want that Claressa rematch, I really do. There's two fights out there for me at the minute, the Shadasia rematch and I think that Claressa rematch is still there. I've waited two-and-a-half, coming up on three years. Now I've lost my world titles and been beaten, it's probably less likely to happen but I do think it's still an option, especially with the Netflix platform."

Marshall described Green as the hardest puncher she'd ever faced. While the 35-year-old was deducted a point for excessive holding early in their bruising contest, two of the three judges deemed she still did enough to edge out victorious.

Marshall had pre-fight concerns about all three judges being from the United States, shared by her manager Mick Hennessy, though they didn't want to attract controversy given his slot on a Netflix bill. Two weeks later, the sense of injustice remains.

"I feel like I was very hard done by. I'm going to America, we've got three American judges and I'm fighting an American. I'm gutted but look, it's boxing. I'm my own worst critic and watched it back a couple of times, even being generous I still have her two rounds down."

She shared an anecdote about her first amateur coach saying that one day, she wouldn't want to box any more, though that's not the case yet.

The bullish Brit remains hopeful that increased exposure from the Netflix platform and MVP's recent spree of signings can work in her favour long-term, given the lack of world-class depth in the heavier weight divisions.
