There's a crowd of 9,000 boxing fans inside the Hydro on
the banks of the River Clyde in Glasgow.
On the undercard, Barnsley's Robbie
Barrett edged out Scott Cardle from Lytham in a hard-fought contest for the
British lightweight title, while Joe Ham won the Scottish featherweight crown
against fellow Glaswegian Scott McCormack.
The atmosphere is building nicely
for the arrival into the arena of Ricky Burns and Julius Indongo at about 22:00 BST.
'Biggest night of my life'

Ricky Burns is under no illusions how important tonight is. The Coatbridge man is only the third British fighter to have won world titles at three different weights.
"If I can unify the division and add another world title to the collection, it doesn't get any bigger than that," said the 34-year-old Scot.
"Mentally, I'm always prepared for whatever's coming my way and I'm not afraid to lose. I will fight anybody they put in front of me. I will always give it 100%. I'm looking forward to it."

First, a bit of news from earlier, as Rio Olympian Lawrence Okolie extended his undefeated professional record to two wins from two.
The 24-year-old cruiserweight downed Poland's Lukasz Rusiewicz three times in the first round.

There was another Team GB fighter on the undercard, with Josh Kelly - known as PBK, Pretty Boy Kelly - making his pro debut.
The 23-year-old welterweight beat Jay Byrne in a six-rounder.

And there was also a win for Robbie Barrett, who claimed the British lightweight title with a majority points win over Scott Cardle.
Post update
We'll have all the build-up to tonight's main fight, while there'll also be updates from Iain Butcher and Charlie Edwards' bout - the pair are already in the ring.
Edwards has a shot at the vacant British super-flyweight title, but Butcher failed to make the weight meaning he won't be able to take the belt even if he wins.
Scot Butcher has won 16 of his 18 pro fights, with two defeats, while Surrey-born Edwards has won nine and lost one of his 10 professional bouts.

Burns will put his WBA super-lightweight belt on the line in Glasgow.
He'll have the crowd, the home backing. But does the 34-year-old have what it takes to become Scotland's first unified champion?
