Kevin Mitchell is down again in the fifth, he's in big trouble here, he was ruthlessly floored...

After hitting the canvas Kevin Mitchell gets up and swaggers a little as if to show he was not hurt. But was he knocked down? Replays show it looks like more of a trip.

Remember as I said earlier, the styles of these fighters means their feet are closer together. It was definitely a trip but the referee gave a count, so it will count as a knockdown.

"It looked like a trip to be honest. It was a close round but I give it to Mitchell 10-9."

Wow, in the fourth we have a man down and it is Kevin Mitchell. It looked like he stepped in and got caught with a blistering left-right...

Since Anthony Joshua is looking to avenge his first loss in the amateurs to Dillian Whyte tonight...

We would like to know a sporting moment where you would like to even the score.

Nice side-to-side footwork from Mitchell but his lap of the ring ends with him cornered... oh dear, Ismael Barroso starts teeing off with gusto.

Right hook, left straight, right straight, it's an avalanche of punches but Mitchell gets some cover behind a high guard and gets out eventually. He won't want many more moments like that.

They find the middle of the ring, left hook from the Briton, no one home. In dives Barroso with a leaping left, gets a bit of his man but not enough. A strange round, Mitchell cornered himself and that will have been seen by the judges.

"I would just say that Barroso nicked that round but the signs are there that Kevin Mitchell is starting to work him out."

As the round closes, Kevin Mitchell leaps in with a right-left combination but the Venezuelan slips it easily. A jab flicked by Ismael Barroso does not get any of Mitchell and again it's a tippy-tappy exchange with nothing big landed.

Kevin Mitchell had a glowing amateur career after winning his first amateur title at the age of 18 and then turning professional straight away.  

However, a defeat to Michael Katsidis at Upton Park, the home of his favourite football team, in 2010 saw things spiral out of control.

He split up from his girlfriend and has said he spent£180,000 on booze and big partiesin the space of just nine months. 

But he quickly got his life back on track and fought his way to two world title shots. Can he earn a third with a win tonight? Surely this is his last chance.

"A difficult round to score that one."

Ismael Barroso is a southpaw - so he leads with his right hand - while Kevin Mitchell is an orthodox fighter - he leads with his left.

The result is both men are stood in a way where their feet are close together. It's a cagey start, no real power punches of initiative seized, very much a range finder of a three minutes.

They touch gloves on the bell. Classy.

The first of 12 rounds is under way, Kevin Mitchell in dark blue shorts with gold trim, Ismael Barroso in red with a bit of leopard print throw in. 

Ismael Barroso has the face of a man who could be punched all day and will just keep smiling back to you.

The Venezuelan is unbeaten in 20 matches.

"It's a big test tonight for Kevin Mitchell. When he lost to Jorge Linares it was a test of his soul. He gave everything the kid did. He just got edged out. 

"A contest like that will take its toll. He's 31 years of age tonight. I want to see how he will respond. I've been watching him train and I want to see what is left in the tank."

Kevin Mitchell hopes that a win tonight will put him on the path to a third world title shot with  WBA world champion Anthony Crolla if he wins the interim world title against Ismael Barroso. 

He lost his first official shot to  Ricky Burns after he succumbed to the power of the Scotsman in the fourth round. 

The Dagenham fighter is in familiar territory tonight - the O2 Arena - as it was the scene of his last world title defeat to WBC champion Jorge Linares. 

But can Mitchell turn is fortunes around and set up a big British clash with Manchester's Crolla? 

So before Anthony Joshua and Dillian Whyte trade leather, we have some cracking bouts on the undercard.

Coming up next is Kevin Mitchell v Ismael Barroso in a lightweight contest which will see the winner lined up to face Anthony Crolla for a world title shot.

Then it's Chris Eubank Jnr v Gary O'Sullivan in a middleweight match full of needle. Then the icing on the cake. It will be explosive.

"Whyte has shown shades of Tyson Fury-type confidence and this in your face insistence that he has enough to take down Anthony Joshua. He might just be the first man Joshua has faced as a professional who genuinely believes he can win the fight."

Mike will commentate on the fight when coverage switches from BBC Radio 5 live Sports Extra to 5 live at 22:30 GMT.

So as tonight is about revenge for Anthony Joshua, why don't you tell me of the one sporting moment you would love to avenge.

Perhaps a match your team should never have lost? Maybe you have even taken part in a contest which still hurts you today.
