Derrick Lewis secured an incredible victory when he came-from-behind to finish Alexander Volkov in the final minute of their UFC 229 clash on Saturday - and he now has a UFC heavyweight world title shot in three weeks' time.

The American power puncher had little name value around the world before Saturday's showdown.

But he won a "performance of the night" bonus for his savage finish and then went viral for giving a hilarious post-fight interview where he told the UFC commentator Joe Rogan his "balls was hot" and that Donald Trump had called to explicitly tell him to "knock this Russian mother f----- out."

Days later, he trebled the amount of followers on his Instagram account - he currently has 1.2 million fans.

And he has now been awarded a world title shot against reigning UFC heavyweight champion Dan Cormier, but the catch is that the fight will take place on November 3, at the UFC 230 event that takes place at Madison Square Garden in New York. This leaves Lewis with less than a month to prepare for the biggest fight of his life.

Dana White reportedly confirmed that "the fight is done," according to ESPN journalist Brett Okamoto.

Prominent MMA reporter Ariel Helwani also tweeted about the event.

Lewis has previously said he wanted to knock Cormier out, and it's all because he apparently "disrespected" Popeyes chicken - a fast food outlet that both heavyweights seem to enjoy.
