David Price provides details on knocking Anthony Joshua down during a notorious 2011 sparring session...
Can you remember the sparring session when you knocked Joshua down?
It was seven years ago, but I remember it well. I was sparring for my first 10-round fight.
So what happened inside the ring?
He fell forwards, onto his face. He went down heavily. He tried to get up but was on unsteady legs, and the trainer pulled him out.
Joshua claimed he woke up in a police cell before sparring you…
I didn't know that, at the time. I don't think the trainers knew. Did he drive up from London that morning? I didn't know.
Did you ever think Joshua was vulnerable?
I don't knock many people out in sparring, with those big gloves. When I did that to him, I wondered: is he fragile? Then I heard he was stopped in the European Championships. But now, he's proving to be okay. He didn't go into a shell, and he isn't gun shy. He got rocked by Dillian Whyte and put down by Klitschko, but he can hold a shot.
Could you tell that Joshua had potential?
Yes. I knew he had something but I didn't know how much. It's hard to tell.
Did Joshua come with a reputation?
I was aware of who he was. He was a two-time ABA champion. I still had one eye on the amateurs, because I hadn't long turned pro.
Did you spar Joshua before or after this incident?
That was the first and only time.
You made this knockdown public last year…
I brought it up to generate interest for his team to say 'we will fight Price'. That was my ace in the pack, at the time.
I had held onto it until the time was right to let the cat out of the bag. Normally, sparring is just sparring. But when there's an opportunity at a world title on the line, I thought I'd get the information out there.
How do you reflect on that knockdown now?
There's no shame in being knocked down by me. If he was knocked down by a light puncher, or a light-heavyweight, then yes.
Did you hear Joseph Parker's team reference you during the press conference with Joshua?
I got a WhatsApp this week saying: 'Joshua is saying how you put him down'. I was sat in a gym, in Liverpool, doing a weights session. I messaged back saying: 'well, he's had the last laugh, hasn't he?'
Why was this incident brought up by Parker's team?
They are clutching at straws. It's funny that the world champion is having to justify his chin.
