Deontay Wilder isn't taking no for an answer ahead of his intended world heavyweight clash with Luis Ortiz in November.

With the winner almost certainly lined up to face Anthony Joshua - assuming he defeats Kubrat Pulev - the New York-based bout was poised to attract serious attention. 

However, the fight has been cast into doubt after Ortiz tested positive for banned substance that he claims is simply blood pressure medicine.

The likes of Tony Bellew and Eddie Hearn have hit out at 'King Kong' over Twitter with the news proving the second time Ortiz has been caught doping.

The unbeaten fighter's victory over Lateef Kayode in 2014 was rendered a no-contest after a positive drugs test after the fight.

It seems Ortiz won't even step in the ring this time, though, with ESPN reporting that the fight has been cancelled as a result of the WBC's findings.

All that considered, you would think Wilder would cherish his own unbeaten record of 38-0 and prepare for a potential unification bout with Joshua. There could even be time for another opponent to be brought in with Dillian Whyte throwing his hat into the ring.

Wilder begs to differ, however, and in a furious rant on Instagram has expressed his unwavering desire to exchange blows with Ortiz, regardless of doping.

It's like Usain Bolt lining up in the Olympics, allowing his opponents to dope and still being confident of victory.

The American ranted: “I will be fighting November 4th at the Barclays Centre.

“Announcement’s coming soon, we’ll see what’s going on, we’ll try to resolve this matter as soon, as fast as possible.

“I know for sure November 4th it’s still going down. It’s all up to the WBC, whatever they want to do with it. I’ve already put in the request that I still want to fight him no matter what.

“These motherf*****s are just gonna do these PEDs.

“If you need some help with me, fine, let’s make this s*** still happen. But it’s not up to me.”

Considering Ortiz's frame and weight already, the image of Wilder lining up against 'King Kong' with banned substances pumping through him is a rather scary thought.

That being said, it's unlikely the WBC will bow down Wilder's wishes unless Ortiz is found innocent in any forthcoming investigation. Besides, you never know, it could do Wilder's chin a favour.
