Just 20 seconds in to round one, Kristian Prenga throws a right hand in followed by an uppercut and down goes Anthony Joshua.
I thought that was curtains. You should have seen the shock from us here in the BBC Sport office.

If you're Tyson Fury, you probably look at that and think 'OK'...
Joshua beats Prenga by knockout
Anthony Joshua speaking in the ring after his knockout victory: "First of all, I want to say thank you to everyone who came out this evening. I appreciate it a lot. I want to give a massive thank you to Prenga and his team for putting up a good fight. It means a lot to them and it means a lot to me and that is why you see what you see in the ring.
"I want to give thanks to God. It was more than me in that situation, it can't just be me in them type of situations. There is a higher power that is calling.
"Shout out to Eddie Hearn for giving me these opportunities and sticking to the cause. Thank you to everyone once again."

Eddie Hearn says the fight between Anthony Joshua and Tyson Fury is "signed".
We didn't see Fury in Jeddah but I'm sure we'll be hearing something regarding that fight in the coming days or weeks.

Anthony Joshua says, "That was Latz, that was Sina" as he takes a pause away from the microphone to gather himself.

On the big screen, Oleksandr Usyk looks shellshocked by what he has seen.
Joshua beats Prenga by knockout
AJ juggling so many styles from amateurs to team Usyk distracts from what he can do in fight or flight mode without overthinking. Does Fury give him the option to reach that before a finish?

Joshua was unbelievably lucky to get through that first round. He has no idea where he was.
In the second, Prenga never threw a shot and allowed himself to be a sacrifice.

Tell you what, I thought Joshua was done in that first round and I reckon Eddie Hearn did too.
That was dramatic and that is why we love heavyweight boxing.

Was it too soon to return for AJ? Physically fit, but he is mentally or emotionally fit?

Joshua v Prenga
Steve Bunce
Boxing expert on BBC Radio 5 Live
He was hurt for the first shot and never really recovered. It was a legitimate knockdown after 20 seconds. He never had his composure.
To be honest, I am absolutely stunned. He looks so vulnerable. I don't like watching it.
Joshua v Prenga
Can Joshua gather himself enough to come back with something?
He can punch, we all know that, but can he land to make Prenga worry?
