Francis Ngannou's lands terrifying blow on punch machine in warning to Anthony Joshua

Francis Ngannou registered a monstrous score on a punch machine after landing a brutal blow.

Ngannou is in preparation for his gigantic fight against Anthony Joshua in Riyadh, Saudi Arabia, on March 8.

He enters his bout with 'AJ' having taken Tyson Fury the distance in their clash last year.

Ngannou dropped Fury as he impressed fans and critics alike with his brilliant performance in his boxing debut.

The former UFC heavyweight champion will look to get off the mark in the boxing ranks when he meets the British star.

And he has sent a terrifying warning to Joshua ahead of their contest next week.

Ngannou showed off his incredible power as he landed a devastating right hand on a punch machine, recording a massive score of 999. Check it out below:

He almost beat Fury in his last fight as former UFC fighter Dan Hardy reckons 'The Predator' will come out victorious against Joshua.

"I'm going with Ngannou genuinely," said Hardy.

"I picked Fury in the last one. I felt Fury was going to be able to catch him fifth or sixth round once he started to get tired. But this for me is a much better match up for Ngannou.

"I feel like AJ's easier to hit, easier to rattle psychologically and I feel like because of the unknown commodity of Francis Ngannou there's going to be a shock to the system."

A win over Joshua could see Ngannou secure a undisputed showdown against the winner of Fury vs. Oleksandr Usyk, which goes down on May 18.

Joshua, meanwhile, is on a three-fight winning streak having lost back-to-back fights to Usyk.

He boasts wins over Jermaine Franklin, Robert Helenius and Otto Wallin.

The 34-year-old rolled back the years to deliver a masterful showing against Wallin, stopping the Swede in the fifth round.
