The fighters are making their ringwalks. First it’s Porter, the two-time welterweight champion, accompanied by the rapper Rapsody as he makes the long walk to the squared circle. And then comes Crawford, ambling to the ring in white robe and black trim to LL Cool J’s I’m Bad.

Hello and welcome to tonight’s WBO welterweight title fight between Terence Crawford and Shawn Porter. Crawford, the longtime champion at 147lbs who’s been on the shelf since a TKO win over Britain’s Kell Brook last year, is out to bolster his claim as the world’s best pound-for-pound fighter opposite Porter, who’s fresh off a dominant win over Sebastian Formella in August.

Fascinating scrap, this. Crawford is a heavy favorite on merit – most oddsmakers list him as a 5/1 favorite – but no one ever looks good against the crafty, athletic Porter, a two-time beltholder at boxing’s glamour division. The consensus is tonight’s showdown will either be a virtuoso performance for Crawford against perhaps the highest quality opponent of his career or an all-out war between two of the best welterweights of their generation.
