Katie Taylor and Chantelle Cameron came in at exactly the same weight at the Mansion House in Dublin on Friday afternoon as a raucous crowd set the tone for tomorrow's showdown at the 3Arena.

Taylor and undisputed super lightweight title holder Cameron both tipped the scales at 139.7lbs ahead of the 140lbs contest.

The home favourite can write another chapter in an outstanding career as she aims to become just the third two-weight undisputed champion ever, joining Evander Holyfield and Claressa Shields in the history books.

It's her first fight on Irish soil since turning pro in 2016 - and anticipation levels are through the roof.

"This is absolutely incredible," Taylor said as supporters whooped and hollered at the weigh-in.

"I can't wait to get a hold of those belts. To bring big-time boxing back to this great nation... this is a nation who loves her sport, loves her boxing. I'm so proud to be here. I'm going to give it my all tomorrow and become a two-weight world champion.

"I'm just so grateful for all the support throughout the amateur days, the pro days the last few years.

"I'm a very, very proud Irishwoman and every time I step into the arena I represent my country.

"I love this nation, I love you guys, and I can't wait to perform again for you tomorrow night."

Taylor was initially slated to face Amanda Serrano on Saturday night in a rerun of their epic contest at Madison Square Garden in April last year – the first women's bout to headline the famed venue.

Taylor won that affair by wafer-thin split decision after withstanding some punishment in the middle rounds and hoped to entice Serrano to Croke Park, only for security-cost issues to scupper the dream.

Serrano’s injury then led to Taylor, somewhat uncharacteristically, taking to social media to call out English fighter Cameron, who gleefully stepped into the breach.

Cameron, who will have height and reach advantages over Taylor, has not been unduly tested in her 17 wins, eight inside the distance, and has seemed unfazed by the hype ahead of the homecoming fight.

"Cool heads in a hot kitchen, it’s just down to business," said Cameron, who claimed all four major world titles last November by beating Jessica McCaskill.

"I’ll bring everything I’ve got."

The main event is expected to begin around 10.30pm.
