Regis Prograis enters the ring wearing his "Rougarou" mask, a fabled, terrifying creature from Louisiana eying Prestonpans prey. What does the Tartan Tornado have in store for him?

Marcus McDonnell is our referee. Let's hope we don't see too much of him. Here we go.

Both men made the 10st limit, Josh Taylor by the smallest margin possible.

As expected, the Tartan Tornado, has the majority of the fans' support.

Here's Buffer again...

"For the thousands in attendance here at the O2 London and the millions watching around the world, ladies and gentlemen let's get ready to rumblllllllllllllleeeeeeeeeeeeee."

Still something special about those words. The crowd, as they always do, lap it all up.

This man is already a winner tonight, who will be celebrating in the main event?

Two perfect records. Twelve of Taylor's 15 wins have been inside the distance, while Prograis has stopped 20 of his 24 opponents. Going to be sensational.

BBC Radio 5 Live

We're now live on BBC Radio 5 Live, so listen to Mike Costello, Steve Bunce and Andy Lee by pressing the play button at the top.

Some more quotes from Josh Taylor, who earlier this week told BBC Sport: "Regis thinks he's a bit of a superstar - he's a bit of a show pony, coming here to a news conference with his shades on. It's raining outside. I don't know what it is but there is something about him that makes me want to take his chin off.

"He's an away fighter; he will be getting a big shock. It might get to him a little bit. I can tell he is nervous when I look in his eyes."

If a shot at two belts and the future opportunities a win presents is not enough, the winner will also claim the World Boxing Super Series trophy for 2019.

"Jump Around" by the aptly named House of Pain is blaring around the arena as we await the fighters for the main event. This is such a tough fight to call - unless there's a draw, Prograis or Taylor is going to lose his unbeaten record. Two undefeated champions go toe to toe.

Here comes Josh Taylor first. This is his first fight at the O2 Arena, and indeed his first fight in London.

For Prograis, all 24 of his 24 fights have been in the United States before tonight.

"The moment we have been waiting for. Undefeated champion versus undefeated champion. Somebody's '0' has to go. Let's get this party started."

Brilliant as always from Buffer.

Five years ago Josh Taylor shared the home stage at the Commonwealth Games in Glasgow with Charlie 'The Mailman' Flynn, who before the action began, delivered his own good luck message tonight...

Singalong time.

"Sweet Caroline," by Neil Diamond rings around the O2 Arena. I don't know how this became the anthem of British boxing, but it always creates a spine-tingling atmosphere any time you see and hear it when watching live boxing.

Both of these can drop or stop the other. But I think this is a fight decided on intelligence, rather than power. I am going just the other way around.

If Taylor can survive the best Prograis has to throw at him, I can see him getting home on a tight call.

I am seeing this as a genuine 50-50. I am leaning very slightly to Prograis for the simple fact I think there is a little bit more that's different about him and I think there is more than one way he can win.

I do think it's a really difficult fight to call, as difficult as any in 2019.

Regis Prograis says he saw one life disappear and a new one begin when Hurricane Katrina decimated his New Orleans home in 2005.

The American - the WBA world super-lightweight champion - was 16 when his country's deadliest hurricane in 77 years killed an estimated 1,836 people.

As Prograis gets ready to face Scotland's world IBF super-lightweight champion Josh Taylor, the 30-year-old says he looks back on a "painful" time that forced him to relocate and ultimately shaped his boxing journey.

"Your whole life is gone, everything you ever knew," Prograis told 5 Live's Boxing podcast. "You knew it will never be the same again but for me, now, it was one of the best things that ever happened to me."

But Prograis has suggested that the Scot, who defeated IBF champion Ivan Baranchyk of Belarus in his World Boxing Super Series semi-final, leaves himself open to punches too much and has weaknesses he can exploit.

Prograis, who took the WBA belt off Kiryl Relikh of Belarus in his semi-final, refuted Taylor's claims about the quality of his previous opponents.

"Of course people want to hurt me, but they can't," he said. "They don't come in there to lose. That's what they sign a contract for - to try to beat me up."

Watch as Josh Taylor accuses unbeaten world title opponent Regis Prograis of having a record "padded against binmen".

"He's had 24 fights, 24 wins against nobody," said Taylor. "I'm going in there to do a job and I just want to get in there and get it done there."

"I've got less experience in terms of number of fights," Taylor, who has won his 15 professional bouts, said during a tetchy media conference attended by both boxers.

"But I believe I've had better opposition and had a great amateur career, I've fought all round the world I've seen every kind of style that's been thrown at me. He's not fought anybody who's been in there to rip his belts off him. Not really any real, live opponents."

"We never took anything off him. We just supported him and gave him goals. And he's still doing it."

Every day for three years, a young Josh Taylor bounded into Terry McCormack's Lochend Boxing Club in Edinburgh.

He came to the gym as a 16-year-old part-time pool attendant, but McCormack remembers a kid who had "nothing" except talent, enthusiasm and a determination to be a fighter.

How has Josh Taylor risen from an Edinburgh hut to the cusp of greatness?

Next up. The main event. Scotland's Josh Taylor, the IBF super-lightweight champion, takes on America's Regis Prograis, the WBA title holder, in the final of the World Boxing Super Series.
