Ryan Garcia furiously denies he took banned substance before Devin Haney fight in series of videos

Ryan Garcia has posted a series of videos on social media after his positive test for a banned substance before and on the day of his fight against Devin Haney - after denying he took any banned substances.

The Voluntary Anti-Doping Association sent a letter to all involved parties on Wednesday, which was reported by ESPN, stating that the Californian boxer had tested positive for the performance-enhancing substance ostarine, both on the day before and of the fight.

Garcia went on to win the fight by majority decision after knocking down Haney in rounds seven, 10 and 11.

After the reports emerged, the 25-year-old repeatedly denied that he had taken a banned substance.

In a video posted to Twitter, he stated: "Everybody knows that I don't cheat. What can I say?

"Why didn't they come out with this before the fight if they found this before? Why would they let me step into the ring as a cheater, then let me come out with the victory and then they post this?

"These are people that are trying to attack me for whatever reason. I've never taken a steroid. I don't even know where to get steroids.

"I barely take supplements. Big lies. I beat his ass, f**k out of here. F**k the haters."

In a separate Instagram Live, which spanned over four minutes, he said: "I don't even know what ostarine is. I was on tequila. If tequila's got steroids, I'm guilty... They're out to get me."

He then made light of the situation by posting a photo of the herbal supplement Ashwaghanda Root to Twitter: "My bad, I shouldn't have took this."

Haney, meanwhile, urged Garcia to 'apologise' to fans: "Ryan owes the fans an apology, and by his recent tweet he still thinks this is a joke. We put our lives on the line to entertain people for a living. You don't play boxing.

"This puts the fight in a completely different light. Despite the disadvantage, I still fought on my shield and got back up! People die in this sport. This is not a laughing matter."
