Errol Spence Jr has doubled down on his intention to move up in weight, following his stoppage loss to Terence Crawford on Saturday. Crawford outclassed Spence en route to a ninth-round win in Las Vegas, becoming undisputed welterweight champion by adding Spence’s unified titles to his WBO belt. At the post-fight press conference at the T-Mobile Arena, Spence expressed his desire to activate a rematch clause. The 33-year-old also suggested that he would prefer the rematch to take place at super-welterweight. And Spence has now updated his Instagram bio to read “154[lbs]”, in reference to his intended new division. “Hell yeah, we got to do it again,” the American said on Saturday (29 July), after suffering the first loss of his professional career. “I’m going to be a lot better, [the rematch] is going to be a lot closer. It’s probably going to be in December, because it’s set before the end of the year.” Crawford, 35, added: “It definitely doesn’t have to be at 147lbs [welterweight]. I’m in the hurt business. One hundred and forty-seven was kind of hard for me, too. “I was already talking about moving up in weight and challenging [Jermell] Charlo, so 154 wouldn’t be out of reach.” American Crawford remained unbeaten with his victory over Spence, in a fight that was five years in the making. What many saw as a 50-50 bout, prior to Saturday, was a one-sided beating by Crawford. Click here to subscribe to The Independent’s Sport YouTube channel for all the latest sports videos.
