Errol Spence Jr has claimed that his bout with Terence Crawford, ‘one of the biggest fights of the century’, may simply be a ‘one-sided a**-whooping’. Spence vs Crawford, a fight first discussed in 2018 and desired by boxing fans ever since, was finally confirmed on Thursday (25 May), with the unbeaten Americans due to clash in Las Vegas on 29 July. Spence Jr, 33, will enter the T-Mobile Arena as unified welterweight champion, while Crawford, 35, holds the WBO title. As such, an undisputed champion will emerge from their contest, as long as it does not end as a draw. “Finally giving the fans what they want!” Spence Jr wrote on Instagram on Thursday. “This one [is] a throwback fight on paper but it could be a one sided a** whooping. One of the biggest fights of the century.” Meanwhile, fellow southpaw Crawford said in an Instagram video: “The wait is over, it’s game time [...] Everybody come out, show support, watch me fry this fish.” Spence Jr and Crawford were in talks last autumn over a November bout, but negotiations fell through, leading the latter to box David Avanesyan in December. Crawford stopped Avanesyan in Round 6, while Spence Jr last fought in April 2022, beating Yordenis Ugas in the 10th round.
