What is at stake at UFC Freedom 250 at the White House?
Ilia Topuria defends his lightweight belt against Justin Gaethje in the main-event. For popular veteran Gaethje, who earned this shot by beating Paddy Pimblett, it is surely a final opportunity to claim UFC gold. But for Gaethje to win, and fly the American flag at the White House, he must overcome the fearsome Topuria who is ESPN's No. 2 pound-for-pound fighter.
Alex Pereira is stepping into a third weight division aiming to create more history against Ciryl Gane. The Brazilian has spectacularly won UFC titles at middleweight and light-heavyweight and is now making his heavyweight debut, with the interim championship at stake. The full title is held by Tom Aspinall who has been sidelined with eye injuries since his last fight, which came against France's Gane.
Heavyweights Josh Hokit and Derrick Lewis earned late call-ups to the card partly due to a request from President Trump, according to Dana White.
