Promoter Ben Shalom says “once in a generation sporting star” Lauren Price will become a “superstar” when she faces Jessica McCaskill on Saturday.
Olympic champion Price, 29, will fight for the WBA, IBO and Ring Magazine welterweight titles at Cardiff’s Utilita Arena.
Price’s bid to claim her first professional world title will be shown live and free-to-air on BBC Wales in a simulcast with Sky Sports.
The Welsh boxer is challenging for a world title in only her seventh professional bout, but Shalom says he is happy to take the risk of matching her with McCaskill, 39, a former undisputed world champion who has not lost at welterweight.
“It’s a risk but Lauren has not lost a round since turning professional,” Shalom told BBC Sport Wales.
“We are going to see a superstar born on Saturday night.”
Shalom said he believes Price can do for Wales what Katie Taylor has done for Ireland as she bids to become Wales’ first female world champion and 14th in all.
“Lauren is fighting a pioneer of women’s boxing, but she is an athlete who breaks records,” Shalom said.
“This is one of the biggest tests we could give Lauren. I think she is just so important for Wales. It’s a huge moment in Welsh sporting history.”
