Standing in Lee Selby's way is American-based Russian Evgeny Gradovich, who has a record of 19 wins and just one (controversial) draw - which came last time out, against Jayson Velez in Nebraska.

He has held the belt for more than two years and has two nicknames - The Mexican Russian and Mini Destructor. I prefer the first one.

He is known as an entertaining fighter, and has been on HBO's Gatti List which recognises the world's five most spectacular fighters.

First up, we're about to see how the fighting pride of Wales Lee Selby gets on in his quest to emulate fellow compatriots Steve Robinson and Howard Winstone by winning world featherweight titles.

The 28-year-old, with a record of 20 wins and just one defeat, is known by some as the 'Welsh Mayweather' because of his showboating style.

Not a bad nickname to have. But what does Selby think about it?

"I wouldn't class myself as the Welsh Mayweather," he said., external "I wasn't always flashy, there's nothing I'd like more than to have a tear-up.

"That's what I did from 10 years of age, just have a scrap. That's what I'd like to do but that won't win fights. The way to win fights in professional boxing is to hit and not get hit, to hit and make them miss and that's what I mould my style on."

BBC Radio 5 live

Let's be honest, it wouldn't be a proper night of boxing without the superb commentary of Mike Costello. BBC Radio 5 live will bring commentary from the O2 Arena from 21:00 BST. You can also listen online and through your mobile phone, connected TV, the app or whatever else you can get rigged up to t'internet.

Former world light-heavyweight champion Nathan Cleverly starts a six-rounder against Czech Tomas Man. And it's all over in about 25 seconds with a brutal bodyshot that has Man on the canvas.

Well, you don't get paid for overtime in this game.

In the opening fight of the night, Dave Ryan was knocked down twice before retaining his Commonwealth light-welterweight title with a technical knockout win over John Wayne Hibbert.

Scott Cardle became the new British lightweight champion after a unanimous points decision over Craig Evans.

And Nick Blackwell stunned John Ryder with a seventh-round stoppage to become the new British middleweight champion.

What's your boxing opinion like? Do you throw right-hand bombs like Anthony Joshua, or do you prefer to be as slick as Kell Brook?

Whatever you want to get off your chest - as long as it's vaguely about boxing - you're in the right place.

Let's kick off by asking you what your ring-walk music entrance would be. I ask this because Joshua offered fans the chance to vote on his arrival music this week.

Me? Being a Mancunian, I'd be straying into Oasis territory.

Evening all. Nice little Saturday night ahead of us, isn't there?

It's almost a year to the day that Carl Froch flattened George Groves. Will tonight's bill at the O2 Arena offer similar levels of excitement and high-class boxing. The sell-out crowd is in place, now it's over to the boys who throw the punches.

What's that I hear? Where's the big, nasty heavyweights?

Well, if big men throwing big punches is your thing Anthony Joshua is in action against durable American Kevin Johnson.

Johnson has called Joshua a "big baby" in the fight build-up. If I'd called Joshua something like that, I wouldn't bother turning up tonight. It would be lights out.

Or will Joshua finally be taken the distance in his 13th fight?

Then there's the business of tonight, when three Brits could end the evening as world champions.

Lee Selby is targeting the IBF featherweight title against Evgeny Gradovich while, in the lightweight division, local hero Kevin Mitchell will hope to end a turbulent few years with victory against Venezuela's WBC champion Jorge Linares.

The headline act? Well, that's Kell Brook who will do battle with fellow Brit Frankie Gavin to decide who sleeps with the IBF welterweight belt tonight, Steven Gerrard-style., external

For the last few years British boxing has been in the shadows. Apart from the obvious few, there has been a lack of world-class boxers and, more importantly, the belts and titles they bring to these shores.

But that's all changing.

Amir Khan is closing in on a mega-fight with the world's best, Floyd Mayweather, while, just last week, James DeGale made history to become the first Briton to win Olympic gold and a professional world title.

There's the simmering rivalry between world super-bantamweight champions Scott Quigg and Carl Frampton, while Jamie McDonnell is becoming a star in the bamtamweight division.

And perhaps we might yet see modern-day great Carl Froch in the ring again...
