Promoter Ben Shalom of Boxxer, who guide the career of former middleweight champion Savannah Marshall, says the big puncher must win her upcoming fight to have any shot of a rematch with Claressa Shields.
Last October at the O2 Arena, Shields outboxed Marshall over ten rounds to unify the middleweight division.
After being unable to get another fight with Shields straightaway, Marshall decided to move up in weight and will now face undisputed super middleweight champion Franchon Crews-Dezurn on June 17.
Shields, a former world champion at 168, could be tempted to face Marshall for a second time if she manages to become undisputed.
"Savannah Marshall is someone we are incredibly proud of as a company. She has gone from never headlining a show to headlining in Newcastle, selling out the O2 in October, experiences her first defeat - which is always crushing - and then wants the biggest fight straight away," Shalom told Daily Mail.
"She wanted to rematch, she felt like she did a few things wrong that others couldn't see and she wanted to out them right. When she couldn't get the rematch, she wanted to step up in weight - which she is much more comfortable at - and take on the very best.
"She's going straight back into an undisputed fight. It's a huge fight for Savannah, it really is all on the line. If she doesn't win this fight, I don't think the rematch with Shields will ever happen."
After the fight with Shields, Marshall lashed out at everyone with respect to the defeat - including longtime trainer Peter Fury.
"We've been fine. I think people didn't get it. I have quite a dry sense of humor and I've been winding Peter [Fury] up since [the fight with Shields]," Marshall told Daily Mail.
"I can see how people took it the wrong way and I did get quite a lot of backlash but you have to think as a pro, I haven't been beaten before. I went through every emotion under the sun. I was convinced I would have beaten Claressa. But, I fell short and it didn't happen for me. As I said, I went through every emotion. I wanted to retire and do this and do that. I felt it was everyone else's fault but my own. But, at the end of the it's only me in the there. It's only me and her. It's not got anything to do with anyone else. Obviously emotions were high."
