Errol Spence Jr and Terence Crawford come face to face for the final time as rivals both make weight ahead of welterweight showdown in Las Vegas

Las Vegas came to the boil on Friday afternoon as Errol Spence Jr and Terence ‘Bud’ Crawford went face-to-face for the final time ahead of Saturday night’s super fight in Sin City.

The two world champions, both unbeaten, meet in a mouthwatering clash to crown a new welterweight king.

A few hours before Friday’s ceremonial weigh-in, in front of a raucous crowd at T-Mobile Arena, Spence hit the scales on the 147lb limit, while WBO titlist Crawford came in 3oz lighter.

The two fighters shared words and a handshake during the final face-off, with Spence – the WBA, IBF and WBC champion – revealing what was said.

‘He should have thanked me for making this s*** happen,’ Spence said. ‘It’s huge and now it’s time for me to put on a big show.’

The thousands of supporters, who queued in temperatures reaching 111 degrees to secure a seat inside the arena, were split between both fighters.

They created a febrile atmosphere as Spence and Crawford took to the stage. ‘Bud’ looked supremely relaxed and confident as he rapped the words to ‘Mr. Carter’ by Lil Wayne.

 The 35-year-old then declared: ‘We’re about to make history, the better man is going to win tomorrow.’
