So much is made of protecting an unbeaten record. Marshall was outclassed by Claressa Shields at London’s O2 Arena in October, but there is little shame in losing to arguably the greatest female boxer in history.
Having said that, we’ve also seen how badly a loss can impact a boxer. When the Shields rematch could not be made, Marshall considered retirement. Tonight we will get answers on whether the motivation is still there.
Franchon Crews-Dezurn isn't your typical world champion.
The 36-year-old turned professional in November 2016 when she fell to a unanimous decision loss against Claressa Shields.
She has only lost once since, however, that defeat against Alejandra Jimenez was subsequently deemed a no contest after the Mexican failed a drug test.
'The Heavy Hitting Diva' won the vacant WBC super-middleweight title in just her fourth fight and she became the undisputed champion via a unanimous decision win against Elin Cederroos last time out.
Outside of the ring, the American is a fashion designer and launched her debut collection late in 2022.
Crews-Dezurn is also making her mark on the music industry.
A former American Idol contestant, she released her debut single 'Secret Place' last week.
Will she hit the right notes in the ring tonight?

The crowd appears to have picked up a bit, with many of those empty seats now filled. There was a solid cheer as Savannah Marshall's face just appeared on the big screen.
There are a lot of happy Liverpool fans who have stuck around after Natasha Jonas' win. Sitting in front row is Liam Smith, who jumped from his seat when referee Marcus McDonnell halted the contest.

Some wise knowledge being passed on backstage from two-time undisputed champion Claressa Shields to Franchon Crews-Dezurn?
Not a bad person for a few last minute tips...
Savannah Marshall boasted a perfect 12-0 record when she stepped into the ring with American Claressa Shields at London's O2 Arena in October.
The 32-year-old had picked up 10 wins inside the distance and was WBO middleweight champion.
However, Shields, who goes by the alias 'Greatest Woman of All Time' (GWOAT), proved too good on the night as she sealed a unanimous decision victory.
When a rematch could not be negotiated, with Marshall saying Shields "outpriced herself", the Briton took a four-month break from training and contemplated hanging up the gloves.
"Retirement was 100% on my mind," Marshall told BBC Sport. "I'd boxed the best in the world. I'd been beat. I wanted to be the best myself, so what do I want to do now? Do I still want to box?
"The reality of it is that I've been boxing for 20-plus years and there comes a time where I thought: If I don't get a rematch, then where do I go?"

Claressa Shields is in the building. The self-proclaimed GWOAT - greatest woman of all time - is having selfies with fans before she begins her stint at a pundit on the TV broadcast.
Actually, I should know better than using the phrase 'self-proclaimed GWOAT'. I once used said that to her in an interview and her reply was: "Why do you Brits say self-proclaimed? I AM the GWOAT - fact" ... I smiled and nodded, nervously.
