Ortiz was ahead in the fight and doing well, but he was clipped with a single right hand at the end of the seventh round - which sent Ortiz down for the full count.

Now Wilder is heading to a rematch with Fury, on a date in February - likely in Las Vegas.

Fury and Wilder first collided back in December 2018, and the contest ended in a controversial twelve round split draw at Staples Center in Los Angeles.

Fury was down twice in the fight, including what nearly became a fight closer in the twelfth and final round. But between those knockdowns, Fury was outboxing Wilder in many of the rounds.

Davison has now worries after watching Wilder's big win over Ortiz.

"I’ve said before, Luis Ortiz is a fantastic fighter but he’s not Tyson Fury. I also learned that he was a different man fight week to what he was to when he fought Tyson," Davison told Sky Sports.

"Tyson 100 percent got under his skin, I definitely saw that in there, which is pretty understandable. Pressure of a big fight around the corner affected him. People will say he looked poor, but he took his time and he did what he was supposed to do.

"Obviously his power is something you have to negate. Mentally, Tyson is the strongest fighter I’ve come across in history and he’s proved that on a number of occasions. How do we do it? I’m not going to say my ideas on how you would do it. But it’s definitely not what Luis Ortiz just did there. Fair play to him, he had a good go but he got complacent and walked straight into distance. That’s a recipe for disaster."
