LAS VEGAS -- Australian heavyweight Tai Tuivasa's first-round knockout on Saturday of former NFL All-Pro Greg Hardy was only bested by his signature celebration.

Tuivasa (12-3), the 28-year-old slugger who walked out to the cage to the tune of "Wannabe" by the Spice Girls, landed a counter left hook to floor Hardy (7-4, 1 NC) before finishing him with hammer punches. But Tuivasa truly gained the crowd's admiration inside T-Mobile Arena at UFC 264 by climbing the cage wall and drinking beer out of a sneaker, which he refers to as a "shoey." 

The win was Tuivasa's third straight as he stepped ever-so closer to heavyweight title contention, capping off a wild 67 seconds in this featured bout on the pay-per-view main card. 

"I want to fight someone in the top 10 or top 15, or something like that," Tuivasa said. "I don't give a f---, I'm just here to do my thing and have fun."

Tuivasa opened the fight with a series of calf kicks but was countered repeatedly with a hard jab from Hardy, which seemed to raise the confidence of the embattled former NFL start. Hardy, whose career as an NFL defensive end ended after a suspension for domestic violence and a poorly handled comeback with the Cowboys, fell to 4-4 (1 NC) inside the Octagon since his 2019 debut.

Hardy, 32, continued to stalk Tuivasa and snapped his head back with a straight right. But Hardy was too aggressive in his pursuit to potentially finish Tuivasa and his two-punch combo attempt was perfectly countered by a stiff left hand from Tuivasa to drop him for good.
