He did hurt Dubois, his legs stiffened and Joshua is a fantastic finisher. He goes for the right uppercut and that is such a risky shot to throw. He's a fraction too slow and Dubois lands first.

Dubois said he wanted to use this fight to legitimise his position as the IBF heavyweight champion.

Remember, he didn't beat a champion to get that belt.

Dubois was handed it and elevated from his position as interim champion after Oleksandr Usyk was forced to vacate.

He has more than legitimised his standing tonight.

Has anyone ever dominated Joshua in that fashion?!

I'd suggest no.

What have we just witnessed?!

Joshua came out and seemed to hurt Dubois at the start of round five but he overcommitted and Dubois found the counter.

A perfectly timed right landed non the temple, Joshua shook it off but another clean right hit the jaw and Joshua went face down.

Joshua tried to get back to his feet but it wasn't happening this time.

It's all over.

Joshua is laid down on the canvas.

Joshua sticks out his tongue with 30 seconds left of the round as the referee pulls the pair apart.

Joshua is in deep, deep water now.

Warrior spirit.

This is one-way traffic.

Joshua goes down again but this time its not called as a knockdown.

There is a moment of confusion as it looks like the referee is waving the fight off but we will continue.

Joshua has been so calm in his last four fights, controlling the pace and distance and making others fight his fight.

AJ stood up well and got caught with some cracking left hooks. He still looks timid, he needs to believe in himself.

Daniel is already huffing.

"Be light on your feet," says trainer Ben Davison to Joshua between rounds.

Joshua replies "yeah".

Joshua looks so slow.

He looked robotic on the ring walk.

Is it that right hand in round one or has he got inside his own head before the fight?

The bell rings and Dubois has two rounds in the bag.
