Fans have shown their astonishment after the UFC 260 card delivered on its promise after a string of blockbuster knockouts, which ended in Francis Ngannou becoming the new heavyweight champion.

The main card started off with Aussie fighter Jamie Mullarkey notching his first win in the UFC after a stunning 40 second knockout.

The Aussie opened the main card and there was fireworks immediately after Mullarkey dropped his opponent with a stunning left.

But two freaky stoppages occurred after the opening fight.

Future star Sean O'Malley stunned fans with a huge knockout, but only after Thomas Almeida survived a brutal head kick.

O'Malley dropped his opponent in the first round with a savage head kick, but chose to showboat and walk off instead of finish Almeida.

But he made no mistake in the third round after a two-strike combo.

However, former light and heavyweight champion, turned commentator, Cormier was stunned Almeida survived the initial head kick.

"I cannot believe he's still standing. I have never seen anyone take a kick like that," he said during commentary.

"The fact that Almeida is still in this fight is insane."

The clash between Vincente Luque and Tyron Woodley started off with immediate fireworks.

Woodley came out swinging and appeared to wobble Luque after connecting with a strike.

But Luque regained his composure and startled Woodley himself.

As Woodley attempted to swing back, he fell into Luque's choke hold and was submitted against the cage.

Fans were rightfully stunned at the all-action first round.

In the finale, Ngannou showed why he is considered the future of the heavyweight division, and the company, after a devastating knockout against Stipe Miocic.
