Chadrac Morris: Ortiz for the win this time watch!

Edging closer to the main event now as the camera cuts away from the final bout on the undercard briefly to catch Deontay Wilder getting gloved up.

Luis Ortiz, meanwhile, was looking cool and calm a little earlier. Perhaps a bit too cool because he was sat with a massive electric blanket over him.

Wilder is brilliant, box office and confusing all in one package.

He reminds me of former Premier League player Paulo Wanchope, who seemed to have arms and legs flying at all angles yet excited people and was a threat.

Why it is so confusing is if I was taking a kid to the gym to teach him how to box, I would start with the fundamentals of transferring your weight from your back foot, up, through your body and out to your connecting fist.

Wilder, by comparison, is in the air, feet off the floor, hits someone with a punch from a crazy angle and they are out. I simply cannot explain that and boxing is the only thing in the world I truly understand.

What I will say is his style guarantees excitement and while Joshua, Fury and Ruiz can all make claims on who is best, Wilder is the most dangerous heavyweight in the world simply because of that one-punch power.

Fully focused.

Villamma: Wilder collecting another KO! Most dominant heavyweight we have ever seen!

When Deontay Wilder won his WBC world heavyweight title, Wladimir Klitschko was still bossing the division. Tyson Fury had not yet got hold of Dr Steelhammer, who he would topple some 10 months or so later.

That means Wilder - who landed his belt in January 2015 - has reigned for four years and 10 months.

Tonight could be the 10th time he defends the green belt. That ladies and gents is some going.

While we are on the subject of clothing, Lennox Lewis is in Las Vegas for this one and the British heavyweight was showing off the quite excellent suit he will be wearing the occasion.

It is lined with the images of all the people he fought in his professional career.

Deontay’s brother Marsellos was on the undercard but his fight didn't last long as he was knocked out by the unheralded Dustin Long.

The 30-year-old had been in control of the six-round cruiserweight clash but was caught by a huge left hook from Long.

It was the second loss of Marsellos' career, taking his professional record to two losses from seven fights.

We've been ticking off the undercard for the last few hours and there is one more fight to go before Deontay Wilder and Luis Ortiz.

Leo Santa Cruz takes on Miguel Flores for the vacant WBA Super Featherweight belt. That fight has just got under way now.

Deontay Wilder has warned viewers not to be distracted by anything else when the fight gets under way because he reckons it could be all over in a matter of a seconds.

"Get your popcorn, get your pizza, go to the bathroom, don't let anyone disturb you," he said.

"Don't drop your cell phone, put it in your pocket, because you don't want to be the one who dropped it and look up and say 'what happened?'.

"As I always say, these guys have to be perfect for 12 rounds. I only need to be perfect for two seconds, and then in the blink of an eye it's bam baby, goodnight!"

Good morning! Manage some sleep or did you stay awake all night? We're back for some more boxing and it is an early morning treat as WBC heavyweight world champion Deontay Wilder faces Luis Ortiz in a rematch at the MGM Grand in Las Vegas.

The two first met in the ring in March 2018 in New York when Wilder stopped Ortiz in the 10th round, although Ortiz had certainly given Wilder a couple of scares before then.

I would suggest going to put the kettle on now and getting a brew sorted because, if Wilder is to be believed, this could be a quick one.

Right then, that was lively and you can read the report on Callum Smith's world-title victory by clicking right here.

We will park this live text for three hours or so and be back and in lively mood for Deontay Wilder v Luis Ortiz.

American Wilder could defend his world title for the 10th time. That is some feat but Ortiz will care little and bring all the guile you'd expect from a schooled Cuban.

We look forward to your company in the early hours but for now... Callum Smith... And still...

A reminder of what our mate Deontay had to say earlier this week: "Don't blink. This will not go the distance so get your popcorn, get your pizza, don't drop your cell phone as you don't want to look up and ask what happened? These guys have to be perfect for 12 rounds, I have to be perfect for two seconds."

You have been warned people.

We've seen Luis Ortiz rock Deontay Wilder before. Can it happen again? Wilder got away with it last time and the test he has since faced against Tyson Fury will surely have made him better again.

Our very own Mike Costello thinks it could still be a tricky night's work for the champion.

Right, so that was decent. And you lucky lot can come back for more with us at around 03:30 GMT for Deontay Wilder v Luis Ortiz.

Not a bad one eh?

It seems the consensus is the gap in scoring was off the mark and it's hard to argue with. In many ways, Ryder was always going to have to do something utterly remarkable in Smith's home city. Some may argue he did but psychology and wider narrative, rightly or wrongly, is always there somewhere in these decisions.

Gerard O'Reilly: What a fight that was, didn’t have it that wide though, a draw would’ve been a fair result.

Jay Hussain: Boxing needs a overhaul in judging. Ryder was the clear winner tonight, fans are robbed once again to keep the money machine going.

So there you go, who do you see Callum Smith in with next?

- Saul 'Canelo' Alvarez

- Billy Joe Saunders

- Gennady Golovkin

Or maybe none of the above. Funny old game this one. Every single time Smith has had a big occasion he has been outstanding. Tonight he was expected to ease home and he was flat. I guess it shows what added edge you can gain when you're under the pump a bit.

Eddie Hearn, speaking to BBC Radio 5 live: "Very close. I probably had Callum nicking it. I thought John Ryder boxed really well. It wasn't a great performance from Callum Smith but that phone will be ringing now.

"I don't think anyone would see that fight scored 117-111. I thought Callum would win the fight but I thought John Ryder was outstanding."
