Gavin McDonnell and Rey Vargas weighed-in comfortably within the super-bantamweight limit.
McDonnell weighed 8st 8lbs 8oz, just 8oz heavier than his Mexican opponent before they contest the vacant WBC title, live on Sky Sports from 8pm on Saturday night.
Luke Campbell was 2oz beneath the 9st 9lbs lightweight limit, with opponent Jairo Lopez coming in at 9st 7lbs 1oz.
Tommy Coyle weighed-in at 9st 13lbs 6oz, within the 10st super-lightweight limit, while Rakeem Noble was 9st 13lbs 9oz.
Doncaster's McDonnell will top the bill as an underdog in his first world title fight, but has warned the unbeaten Vargas not to expect an easy night.
"People and fighters say to me, you look easy, you don't hit hard, and then they get in and have a bit of a shock," McDonnell told Sky Sports.
"I have proven that over time and this Saturday, if Rey Vargas hasn't prepared, or underestimates me in the slightest, I'm going to make him pay."
