Time for the national anthems. Hairs on the back of the neck stuff.
Wearing a menacing red and black get-up, which covers the majority of his face, KSO steps into the ring.
A man who means business.
He's blown Logan Paul out of the water with that ring walk and outfit.
He's got the gear, that's for sure.
The legendary Michael Buffer introduces KSI to the crowd.
Then it's over to rappers Rick Ross and S-X.

Kritikul: Really looking forward to this! Been a fan of KSI for a few years - Come on KSI!
The lights do down for KSI.
The only thing illuminating the arena is a big screen which whips the crowd into a frenzy.
Oh, and thousands of flash lights from mobile phones.
It's loud in the Staples Center. Yellow strobe lights greet the arrival of Logan Paul, who is booed as he walks to the ring.
He's wearing a sparkly American flag-style hoodie.
He's done away with the mask he wore in the first fight. You know.. the one which made him look like he was about to do some decorating.

Back in the 1990s, some of those amazing Mike Tyson fights in Las Vegas, you would see the really big names in Hollywood wandering in ringside. This atmosphere tonight is very much like that, everyone looking around and turning their heads, with the big Youtube names filing in and taking their positions.
We're almost set for the ring walks.
Talking - done. Undercard - done.
Let's settle this.

Helloworld: I don’t follow boxing or Youtubers but your live commentary is giving me such much life during my insomnia. Haven’t slept at all but I’ve swotted up on KSI and Logan Paul that’s gotta come in handy one day.
More dressing room shots. Logan Paul drinks from a bottle of water which is almost the same size as a mini fridge. Maybe it is a mini fridge. What's wrong with a sports bottle?
KSI practises throwing some jabs with his right. No sign of the left. Keeping his powder dry?
Some big names sitting in the Logan Paul corner tonight...

That floating fight was pretty eventful!
Jonathan Batista was disqualified at the end of the first round for throwing punches at Nikita Ababiy once the bell to signal the end of the round had sounded.
Scenes.
Logan Paul weighed in heaviest for this fight, at 199.4lbs - just short of the 200lb cruiserweight limit. KSI was 193.2lbs.
That's not a significant difference though. Nothing a multi-pack of crisps and some dips couldn't even out.

Bobby: Enjoying the commentary. Chunkz seems a cool guy & giving good insight, Buncey doing his usual thing & the Scottish dude [Calum McNeish] finding some interesting fans in the crowd.

One of the best fighters in the world at the moment, Regis Prograis, has just walked in and not one person looked up or noticed him in this arena.
And yet, every single Youtuber that has walked past has been spotted.
That is quite amazing.
Just when we thought we were set for the main event, they've thrown in a floating fight.
I'm noticing a trend on the thumbs up/thumbs down icons in this page.
You're all backing the Brit, KSI, aren't you?!
So, it seems, is the crowd. And in Logan Paul's home country. That's gotta sting.
As expected, Haney gets the decision to retain his WBC world lightweight title. Speaking after the fight, Haney says he dislocated his shoulder early in the fight.
And he still went 12 rounds. And still won. And still looks like he's nipped out for a loaf.
Nails.
We're almost set for the main event.
On the undercard, American Devin Haney has just finished making the first defence of his WBC world lightweight title against Dominican Republic's Alfredo Santiago. We're going to the judges, but Haney should get this.
It's not been a classic though, with boos greeting the end of the fight.
