The historic women's triple-header of world title fights is on for Saturday at the SSE Arena in Wembley, as all four fighters in the card's top two bouts made championship weight while Rachel Ball will be eligible for an interim title against her late replacement opponent.
Katie Taylor (16-0, 6 KOs) defends her undisputed lightweight championship against mandatory challenger Miriam Gutierrez (13-0 5 KOs), and the Irish champion tipped the scales at 134lb 7oz, pretty much exactly where she wanted to be within the 135lb limit, while promoter Eddie Hearn struggled to hold all of her various belts.
Spain's Gutierrez weighed just one ounce lighter at 134lb 6oz for her chance to shock the world and conquer the lightweight division in one fell swoop. The fight will be contested over 10 two-minute rounds and will main event the show.
In chief support, Terri Harper (10-0-1, 5 KOs) defends the WBC and IBO super-featherweight titles against Spanish-Norwegian challenger Katharina Thanderz in another battle between undefeated competitors, also over 10 two-minute rounds.
Britain's Harper weighed in at 129lb 5oz while Thanderz came in slightly higher at 129lb 10oz, both neatly inside the 130lb limit. Harper hopes to notch her first win as world champion, after being held to an exciting draw by London 2012 Olympian Natasha Jonas last time out.
And while Rachel Ball (6-0, 1 KO) will indeed round out the triple-header with her own title challenge, earned by way of her surprising Matchroom Fight Camp victory over highly-rated prospect Shannon Courtenay, the circumstances have changed.
Her initial opponent for the vacant WBA bantamweight title, Australia's Ebanie Bridges, sustained an arm injury just days ago. Now, Ball will face Argentina's Jorgelina Guanini (9-1-2, 1 KO) for the interim WBC super-bantamweight belt, the full version of which is currently held by Guanini's compatriot Yamileth Mercado.
The two sides had agreed to a weight discrepancy prior to hitting the scales, with Guanini permitted to weigh slightly more due to the last-minute nature of her being required to step in.
However, only Ball can win the interim title on Saturday, after weighing 121lb 9oz to Guanini's 125lb 7oz.
Opening the show will be light-heavyweights Thomas Whittaker-Hart (4-0, 2 KOs) and Jermaine Springer (7-1, 1 KO). Their eight-rounder is on as planned after Springer weighed in at 173lb 4 oz while Whittaker-Hart had to strip down to get a reading of 174lb 9oz after his first attempt came in two ounces over the 175lb limit.
Kash Farooq (13-1, 6 KOs) hopes to finally be back in action after some of the worst luck of any boxer hindered by injuries and/or the COVID-19 pandemic over the last 12 months. He will face a late replacement in Angel Aviles (20-5-1, 6 KOs) in a bantamweight 10-rounder.
Farooq weighed 117lb on the button, while Mexico's Aviles, who also had the blessing of his opponent's team to come in over the limit as a late replacement, was two pounds above the traditional 118lb bantamweight ceiling at 120lb.
And in what could be a show-stealer between two super-middleweight prospects who clashed verbally at the final press conference, it's unbeaten John Docherty against Jack Cullen.
Scotland's Docherty (8-0, 6 KOs) weighed 166lb 9oz while "Little Lever's Meat Cleaver" Cullen (18-2, 9 KOs) hit the scales slightly heavier at 167lb 7oz, both inside the 168lb divisional limit.
