Logan Paul's tactics are dodgy - low hands and allowing KSI to swing clubs.
This is frenetic. KSI looks like he's going to lift Logan off his feet if he connects. Huge shots.
Yet Logan is nimble on his feet. He's not walking in treacle like the first fight.

Defence is going to win this fight but Logan Paul's left hand is so worryingly low in this early round.
Wow. That was good.
Back to the corner for some water, Vaseline and a pep talk.

Logan Paul's left hand is a bit low - KSI's right looks strong and it could've been all over within 60 seconds with that hit from KSI.
Logan tags KSI with a jab. But that's the shot of an amateur.
KSI is going for the knockout... but does he have the engine to sustain it?
Another booming right from KSI. He's swinging like a rusty gate.
KSI throws a right which clips Logan's ear and follows up with a left. The American is ever so slightly rocked.

I'm so nervous but it's all about now in the ring for KSI.

Proper rocking in here now!
Logan Paul is coming forward, hands down, but KSI is countering with some booming rights. Both fellas want a tear-up. It's not going to be a tentative opening round.
We're up and running.
Youtube subscribers mean so little over the next 18 minutes.
Not when someone is clubbing right hooks to your jaw. You're on your own, fellas.
KSI looks so mean. So menacing. So focused.

We've still not seen KSI's face - he's yet to remove his mask inside the ring.
Even Youtubers react when Michael Buffer screams 'Let's get ready to ruuuummmmbbblllle'.
He could stir a sloth into life.
Nothing gets going in boxing until Michael Buffer says so.
And he's about to say so.
Come on Qaaltagh - let's enjoy the spectacle. We're here now.

Qaaltagh: Can someone remind me why anyone should care about this fight or in actual fact, why either of these two are seen as anything other than clowns? I knew it was easy to become a celebrity but... Seriously?
Logan Paul's the villain here tonight, no doubt about that.
He's booed again when his face is shown during the anthems.
Ouch.
Logan Paul fixes his gaze, then closes his eyes as the Star Spangled Banner is beautifully sung. Red, white and blue lights momentarily everywhere.
