Chantelle Cameron and Katie Taylor were once again well under the divisional limit for their second showdown between undisputed champions.

It was all business throughout fight week and during an intense staredown ahead of their anticipated rematch this Saturday on DAZN from 3Arena in Dublin. England’s Cameron was 139 ½ pounds in a bid to retain her fully unified junior welterweight crown. Taylor—the 37-year-old legendary figure from Bray—was 139.6 pounds in a bid to avenge her lone career defeat.

Both fighters were 139.7 pounds ahead of their first meeting, which saw Cameron spoil Taylor's long overdue homecoming with majority decision win on May 20 at this very same venue.

Cameron (18-0, 8KOs) will attempt her sixth overall defense of at least one junior welterweight title and second as undisputed champion. The 32-year-old from Northampton, England soundly outpointed undefeated Adriana dos Santos Araujo in their October 2020 vacant WBC title fight. She added the IBF belt in a ten-round victory over Mary McGee in their terrific October 2021 unification.

Saturday will mark her third straight fight versus a reigning undisputed champ. She defeated fully unified welterweight queen Jessica McCaskill, who moved up in weight for their four-belt junior welterweight championship last November 5 in Abu Dhabi. Cameron’s win over Taylor marked the sport’s first-ever meeting between two undefeated, undisputed champions in the multi-belt era.

The bout was happenchance. Cameron replaced undisputed featherweight champion Amanda Serrano, who withdrew from her May 20 rematch versus Taylor due to a pre-existing injury which didn’t heal in time.

Taylor (22-1, 6KOs) was adamant about facing the toughest possible opponent for her long overdue Ireland homecoming. The legendary Irishwoman from Bray called out Cameron, in a bid to enter a second 140-pound reign and become—at the time—the sport’s second-ever two-division undisputed champion.

It didn’t happen that way for Taylor, who suffered her lone career defeat. She was equally persistent to run it back with Cameron as she was about taking on that challenge in May.

Taylor now has the chance to become the sport’s third two-division undisputed ruler. Terence Crawford (40-0, 31KOs) joined Claressa Shields (13-0, 2KO) on that stage after his July 29 ninth-round stoppage of Errol Spence to fully unify the welterweight division. The 37-year-old icon remains the undisputed lightweight champion, with those belts not at stake with Saturday’s bout taking place above the 135-pound divisional limit.
