Carl Frampton and Scott Quigg both scaled inside the 122 pound limit as the pair of fierce rivals took to the stage in Manchester.
The IBF and WBA super bantamweight title holder weighed in as a huge crowd watch on, with Frampton hitting 121.7 and Quigg making 121.6 respectively.
Michael Buffer led the ceremony, which largely went without incident, as the UK braces for the biggest event of the year so far on Saturday night at Manchester Arena.
One small talking point was a shoving match between trainers Shane McGuigan and Joe Gallagher whilst jostling for position, although on the whole the weigh-in passed peacefully.
Frampton and Quigg held a near two-minute staredown before flexing in front of the chanting fans in the last of the pre-fight rituals until the first bell.
Sky Sports Box Office will transmit the bout in the UK, whilst Showtime hold rights to duties in the US.
