UFC on ESPN 23, also tagged as UFC Vegas 25, will take place on May 1, 2021, at the UFC Apex facility in Nevada, United States. The event will be headlined by Dominick Reyes and Jiri Prochazka, who are ranked No. 3 and No. 5 in the divisional rankings, respectively.Unlike the last event (UFC 261), fans will not be allowed to enter the arena. However, Dana White has assured that he will try his best to allow a full-capacity crowd to attend non-PPV events.Reyes and Prochazka were originally scheduled to headline the February 27 card. The bout was canceled after Reyes sustained an injury that forced him to withdraw from the fight. Consequently, Jairzinho Rozenstruik vs Ciryl Gane was pushed up the card and was announced as the main event fight.Locked and laser-focused ⚡️ [ 🇨🇿@Jiri_BJP | #UFCVegas25 ] pic.twitter.com/ootJKndHkD— UFC (@ufc) April 29, 2021UFC fight tomorrow: Reyes vs ProchazkaDominick Reyes vs Jiri Prochazka is considered an instrumental clash for the future of the UFC light heavyweight division.
