Terence Crawford defends his WBO welterweight title against Shawn Porter on Saturday in the main event of a Top Rank on ESPN+ PPV card at Michelob ULTRA Arena at Mandalay Bay in Las Vegas (9 p.m. ET).

Crawford (37-0, 28 KOs), 34, of Omaha, Nebraska, won the belt by stopping Jeff Horn in 2018. In his most recent fight in November 2020, he defended the title in a fourth-round TKO victory over Kell Brook, his fourth consecutive defense. But Porter is considered the toughest test of Crawford’s career so far, and Crawford understand the challenge.

“I respect everything that Shawn does. Shawn is athletic, he can box, he can bang, he can move around in the ring, he can cut corners and take angles,” Crawford said on Wednesday’s news conference. “I’m not going to sit here and say that I don’t respect anything that he does. I’m just going to say that I do a lot of things better than Shawn.”

Porter (31-3-1, 17 KOs), 34, of Akron, Ohio is a two-time welterweight champion who has victories over Devon Alexander, Paulie Malignaggi, Adrien Broner and Danny Garcia, among others. He lost close fights challenging for titles against Errol Spence Jr. and Keith Thurman, and aside from being the underdog against Crawford, Porter is confident he can leave the ring with a victory.

“He is a dominant fighter. Everyone he gets in the ring with, he dominates,” Porter said in a recent news conference. “I want to be the one fighter that he can’t dominate. Everything that is required to beat Terence, I got it. It’s time to take on this challenge.”

Johnson scores TKO victory in debut

Tiger Johnson dazzled in his pro debut and poured it on late for a big first victory. The welterweight prospect unleashed some big right hands to stop Antonius Grable in the first fight of Saturday’s Terence Crawford-Shawn Porter undercard.

Johnson, who fights out of Cleveland, Ohio, forced a stoppage at the 1:54 mark of the fourth round. Earlier in the round, Johnson scored a knockdown when a right hand popped the fighter out of Sarasota, Fla., and Grable’s gloves touched the canvas. Grable (3-2-1, 3 KOs) was hurt again seconds later and the referee jumped in to stop the fight.

After the stoppage, Tiger went over to the ESPN broadcast crew and leaned over the ropes with a message for tonight’s announcer Timothy Bradley Jr.: “I’m here.”
