Former UFC flyweight and bantamweight champion Henry Cejudo has backed Conor McGregor to knock out Dustin Poirier when they face off at UFC 257.

This will be the first time that McGregor fights in the lightweight division since he lost to Khabib Nurmagomedov in 2018. The Irishman has not won at the division since 2016, when he defeated Eddie Alvarez.

His bout with Poirier, a rematch of the 2014 encounter which McGregor won, will be his first for 12 months, with his last fight coming when he triumphed over Donald Cerrone in the welterweight division.

But Cejudo, who labelled the Irishman ‘McTapper’ in reference to him tapping out against Nate Diaz and Nurmagomedov, backed McGregor to make a triumphant return.

Speaking in a video on Twitter, Cejudo admitted he felt it would be a quick match.

“Main event the ‘McTapper’ versus Dustin Poirier. I’m going to have to go with the ‘McTapper’ man,” he said.

“As much as I don’t want him to win, he’s got it in him. There’s a reason he is fighting Poirier for the second time.

“He’s got better striking, he’s a better counter puncher and I really do think he is going to finish (Poirier) in the first minute or for sure the first round.”

Cejudo is not the only one who is backing McGregor to emerge victorious from the highly anticipated bout.

Former interim lightweight champion Justin Gaethje has also shared his belief that prediction for tonight’s highly anticipated ‘McGregor vs. Poirier 2’ fight at UFC 257.

“I don’t know. This is two really high level fighters now,” Gaethje said in an interview with Helen Yee.

“Conor is really good and I do see him probably winning. I don’t know, it will be interesting to see if Dustin rises to the occasion.

“What’s different is their mindsets because of the places they are, the places they have gone since then. They are much different people since that (first) fight. That will be interesting to see.”
