The T-Mobile Arena in Las Vegas was once again graced with a crowd for UFC 285 on Saturday night. The exciting card was headlined by Jon Jones' heavyweight debut against Ciryl Gane with the vacant UFC heavyweight title on the line. Four out of five main-card bouts ended in submissions as 'Bones' returned to the octagon after a hiatus of three years.While the showing was absolutely unreal from 'Bones', the main-event lost some of its charm due to its short nature. The MMA G.O.A.T contender made quick work of 'Bon Gamin, effortlessly taking him down and securing a guillotine submission all in hardly two minutes.UFC@ufcTHE GREATEST OF ALL TIME IS NOW THE HEAVYWEIGHT WORLD CHAMP JON JONES SUBMITS CIRYL GANE!! #UFC2856758218553THE GREATEST OF ALL TIME IS NOW THE HEAVYWEIGHT WORLD CHAMP 🏆 JON JONES SUBMITS CIRYL GANE!! #UFC285 https://t.co/JOiAnweVJ5Jones called out former UFC heavyweight champion Stipe Miocic in his post-fight interview.Valentina Shevchenko looked to defend her flyweight title for the eighth consecutive time against Alexa Grasso in the co-main event of the night. While Grasso hurt Shevchenko with a 1-2-3 early on, 'Bullet' strongly bounced back to dominate the Mexican on the ground in subsequent rounds.Grasso successfully stubbed two of Shevchenko's takedown attempts in the fourth round before completely turning the tables. Capitalizing on a missed spinning-back kick from 'Bullet', Grasso took the champ's back with amazing deftness and went on to sink in a rear-naked choke. While Shevchenko's tap did not come immediately, it was a mere eventuality considering how powerful the choke was. Grasso became the first female mexican UFC champion and the first fighter to submit Shevchenko.Danny Segura@dannyseguratvAlexa Grasso is UFC champion.Mexico has now the most champions in the UFC with 3 – Grasso, Yair Rodriguez, Brandon Moreno.UNREAL.
