At UFC 274, only one competitor will compete for the UFC lightweight championship. At Friday's weigh-in, defending champion Charles Oliveira failed to meet the 155-pound weight restriction. Oliveira will be stripped of his championship and ineligible to win it back in the main event. As a result, only his opponent, Justin Gaethje, is in the running for the championship. Oliveira started out weighing 156 pounds. In a later trial, he stripped nude but was still a half-pound above the tight 155-pound weight limit. "Do Bronx" was given one extra hour to lose the extra weight. Non-title fights feature an extra one-pound weight allowance, which means a boxer may weigh as much as 156 pounds for a lightweight fight or 171 pounds for a welterweight fight. Fighters contending for a UFC championship are not granted this leniency. https://twitter.com/aaronbronsteter/status/1522636763629424640?ref_srctwsrc%5Etfw%7Ctwcamp%5Etweetembed%7Ctwterm%5E1522636763629424640%7Ctwgr%5E%7Ctwcon%5Es1_&ref_urlhttps%3A%2F%2Fwww.cbssports.com%2Fmma%2Fnews%2Fcharles-oliveira-misses-weight-for-ufc-274-main-event-loses-lightweight-title-on-the-scale%2F Read This:-UFC 273 results: Khamzat Chimaev wins the war against Gilbert Burns According to Yahoo Sports' Kevin Iole, the organization confirmed following the weigh-ins that if Oliveira wins the fight on Saturday, he would be named the No. 1 contender for the vacant title and will fight the next challenger for the belt at a later date and location.
