These heavyweights are big and slow (jokes).

How quick are you? Take a look at the video below and send your 12-second challenge video to #bbcboxing.

We're waiting.

Here's how these line up.

It's worth remembering both have been in with big names.

David Price took on Alexander Povetkin, Dave Allen has been in there with Luis Ortiz.

Price is notably bigger and hits harder you'd have to say but Allen has shown he can keep going into later rounds.

So who have you got? Tweet #bbcboxing.

Promoter Eddie Hearn, who recently signed Joseph Parker to his stable: "It's a great fight. That win showed the hunger of Chisora tonight. There's something about him at the O2.

"He is a massive fans favourite and has given so much to British boxing and it's not done yet. Let's do the Parker fight, let's go."

This is exactly how we'd all react if Chisora's right came at us.

Dereck Chisora's trainer David Haye: "He needed a spectacular performance.

"He wants that Joseph Parker fight. I spoke to Parker and he said to my face, 'make the fight, I want the fight'. It's an easy fight to make."

That was Chisora's 31st win from 40.

Here's the man himself:

"I wanted to pull out of camp then the last four days everything came together. I'm happy about that.

"Age is nothing but a number. I'm 35 but I feel like I'm 16. I still want to fight the big fights."

On being the bad guy in the past: "I like to fight. If I have to be the bad guy I don't mind. I love being in the ring

"We want to get Joseph Parker now. As long as he doesn't run like a Australian chicken (he's a New Zealander)."

Ant Middleton - from SAS Who Dares Wins - looks like he could throw a good right hand.

Ellie Goulding - of pop song fame - loves a bit of boxing and throws a few punches in the gym from what I'm told.

Neither probably cracks as hard as Dereck Chisora just did.

I would love - and I mean love - to see Chisora on Middleton's SAS show.

The Brit's wide right after a left hook leaves Szpilka seeing stars.

The Pole slumps to the canvas and the medical team rush on to see if he's OK.

It's a few seconds before Szpila The Pin gets up.

Brutal!

By the way, if you want to do your homework on both Dillian Whyte v Oscar Rivas and David Price v Dave Allen then have a read of Luke Reddy's preview piece.

We'll then come round to your home and ask you questions about it.*

*That won't actually happen

Dereck Chisora's ring walk sees him enter the arena wearing a Union Jack bandana wrapped around his face and to the sounds of the Eagles' Hotel California - obviously, they didn't play all six minutes and 30 seconds of it.

So David Price v Dave Allen is coming up after Dereck Chisora v Artur Szpilka.

Basically Price wants to see off the "White Rhino" inside the first few rounds. Note how many time he says "Dave Allen".

"My best chance of beating Dave Allen will probably be in the opening few rounds so it’s going to be fireworks from the first bell.

"I'm expecting fireworks, it’s as simple as that. It’s going to be a great clash of styles. He thinks I’m made for him, I think he's made for me.

"He says he’ll stop me in three, I’ll stop him in two. Dave Allen is a durable fighter but I can knock anyone out and I want to knock Dave Allen out. That’s the plan, to go out to try and stop him.

"We’ve worked on a lot of things to deal with Dave Allen and I’m confident what we’ve worked on is going to be successful on the night. I’m just focusing on doing what I want to do on the night and that’s to get in the ring and knock Dave Allen out which I believe I’m fully capable of."

Boxing superstar Vasyl Lomachenko is at the O2 Arena. You'll have likely heard about the man who collects world titles like marbles.

Earlier today it was confirmed he will fight Britain's Luke Campbell at the O2 on 31 August. Guess who else is at the venue tonight?

Yep, Luke Campbell. Might we see a face off to get us all talking?

As we said in our last post, send us your attempts, just like Marcos has.

I think he may be one of the quickest we've seen so far...

Now before this live takes off with heavyweight action, can I point you n the direction of our new 12-second challenge?

This will be updated each month with new fighters as we're going to keep an ongoing leaderboard.

And, crucially, we want you to send us your own attempt to #bbcboxing. Film it, get your mates to have a go and we will make something with your efforts in the weeks to come.

Richard Riakporhe holds on to his WBA Inter-Continental Cruiserweight with a points win over previously unbeaten Chris Billam-Smith.

It a stamina-sapping contest which was close throughout but the Walworth-born fighter is given the decision.

Del Boy! Del Boy!

He's still around, a part of the heavyweight furniture you would say. Seeing him on an undercard at a British venue is like seeing a tin of Family Circle at the local newsagent. Familiar.

He wants a fight against former WBO champion Joseph Parker, but tonight will look to see off Polish southpaw Artur Szpilka, whose suffered three losses in a 11-year career.

We will have updates from that fight.

The undercard has included the WBA continental cruiserweight smash up between Lawrence Okolie and Mariano Angel Gudino.

Above is a photo of Gudino, who was stopped in the seventh, stunned to learn from the Brit that Shane Lowry has a four-shot lead in The Open.
