Terence Crawford stops Errol Spence to win undisputed welterweight championship – as it happened

• Crawford beats down Spence to unify welterweight titles
• Ohama fighter stakes claim was world's best pound for pound

Here comes Spence! The WBA, WBC and IBF is making his way to the ring alongside Dallas rapper BigXthaPlug. This ends what's been a bit of a mystery. The champion traditionally enters the ring after the challenger. But what happens when both fighters are champions? Even though Spence was the A-side' of the promotion, with his name appearing first on the bill, they agreed to flip a coin to determine who would walk out second (and be announced first).

Crawford chose heads and won the toss, which took place at Thursday's final press conference with Mike Tyson doing the honors, but he declined to say which option he'd choose.
