UFC 274 -- Conor McGregor among stars reacting to Michael Chandler's sensational KO kick of Tony Ferguson

UFC 274 returns to Phoenix for the first time since 2019 with an action-packed main event. Charles Oliveira faces No. 1 lightweight contender Justin Gaethje in a title fight, but only the latter has a shot at claiming the belt. Oliveira failed to make weight Friday, which meant his title will be stripped «upon the start of the main event headliner,» according to the UFC in a statement.

Although he won't get the opportunity to properly defend his championship, Oliveira entered Saturday with momentum. He won 10 straight matches, his last being a submission victory over Dustin Poirier in December. Before the fight, Oliveira's 18 finishes and 15 submissions were the most in UFC history, per ESPN Stats & information.

Gaethje comes into UFC 274 having won five of his prior six matches. His latest match was in November, when he won via unanimous decision against Michael Chandler. Gaethje knows how to hit, having landed 7.5 significant strikes per minute at a 60.1% rate, both the best in his division.

But before Gaethje and Oliveira's fight, Chandler's bout against Ferguson was a thrilling affair. It ended in an instant, as the 36-year-old fighter landed a vicious front-kick in the second round that knocked out Ferguson.

During the postfight interview, Chandler called out former UFC fighter Conor McGregor. The Irish mixed martial artist was aware of Chandler's victory Saturday, tweeting that he is down to fight Chandler.
