Ricky Burns has started the 11th at a frantic pace. Maybe a sign his corner thinks the decision is not going his way.

Earlier on...

Lawrence Okolie took the EBU European cruiserweight title from Belgian Yves Ngabu, who came into the fight with a 20-0 record.

The fight was stopped in the seventh round after the 26-year-old landed a left hook and then a big right hand which left Ngabu unsteady on his feet.

"I could hear him get more and more tired," Okolie told Sky Sports. "If I hit any cruiserweight on the chin then they're going to go."

It has been scrappy, not too many eye-catching successes, but two men still at the top end of their games, especially the Selby jab.

Enthralling, but not out-of-the-seat stuff. Two to go.

A sweeping left hook from Selby thwarts a Burns attack, but it is not long before Burns unleashes a three-punch combination. But the Selby defence is strong, with the shots bouncing off the fists, not the face.

Ricky Burns is the one smiling a lot in the ninth, which has been a bit scrappy.

Tony Sims, in the Burns corner, tells his man that he "needs to push on" and urges for more variety, with the uppercuts a potential route to glory. Three to go.

Some more afters in round eight, this time a left hook from Selby which bounced off the side of the Burns head seems late. Four rounds to go though and you could still make a case for either man winning.

Into the "championship rounds". Both men have been here many times, obviously. Whoever finishes stronger could win this one.

Back stage, Dereck Chisora is working on his power punches. David Price had better not be on the end of anything like this or it will be all over.

That one is next up.

That seventh was a good round for Burns, probably what he needed as Selby had just been threatening to move clear in this one.

Early in the seventh, Ricky Burns is warned for leading with the head. The frustration appears to be growing from the Scottish fighter.

But then a good flurry from Burns, maybe some of his best work of the contest, landing one, two, three head shots as Selby gets on his heels trying to avoid the damage.

Earlier this week, Lee Selby called this contest a career-defining fight...

"Ricky Burns is a great fight for boxing fans; it is a real 50/50 fight," Selby said. "It's a former three-weight world champion against a former world champion and that makes for a great night.

"There is a lot on the line, career-defining you could say. If Ricky Burns loses to me then it looks like retirement for him.

"If I lose, then I have to be realistic and say it doesn't look like I am going to win another world title and I will have to drop down a level. It's the only way to look at it. I am a realist and if I can't beat Ricky Burns I am not going to beat one of the world champions.

"I was IBF featherweight champion and retain a good ranking with them. As long as I beat Ricky Burns I should be in a position to be in a final eliminator for a world title shot and that is what I am looking to do."

Here comes the controversy. Round five, the bell might have just gone. Selby swings at his opponent with a right to the body, Burns is furious though and then throws a punch at Selby's head.

The referee has to come in and separate then and try to keep things under control.

Both men then get a stern talking to.

Four gone and you would be a brave person to say who is winning this one. As expected from two of the sport's best craftsmen, both are having success at times.

Earlier tonight... Conor Benn defended his WBA continental welterweight title with a fourth-round knockout of Belgian Steve Jamoye.

The 23-year-old, the son of former middleweight and super-middleweight world champion Nigel Benn, ended his opponent's night with a fierce right hook.

That's 16 contests, 16 wins for Conor Benn.

There is a large crowd ringside at the O2 already. No waiting around at the bar, this is a fight between two of the best British boxers in the past 10 years.

Burns has an incredible 43 wins under his belt, from 51 contests, while Selby has only lost twice in 29 bouts.

Two rounds gone in London, and not much in it at all. A clash of heads, followed by a tasty sweeping left hook from Lee Selby leaves some damage around the right eye of Ricky Burns in that second round.

There's still a lot riding on this one though, as the winner of this bout, will put themselves in the frame for a world title fight, says ex-WBO champion Alex Arthur.

"It's not a fight that either of these guys need, but it's one they both want," he told BBC Scotland.

"That is testimony to their character. These are both really proud ex-champions and still want to go on and challenge for titles. Both, in reality, leave themselves in a pretty good spot to start shouting for a title shot if they win. If they look good, something could happen for them."

Former IBF featherweight champion Lee Selby says he never thought he would end up fighting former sparring partner Ricky Burns.
