Taking to social media, the 34-year-old American wrote: “I’m gutted to deliver this news to you all but I will not be fighting at UFC 303 due to consuming a banned substance.

“I did not do this intentionally and I am doing everything I can to get this situation taken care of.

“I was using a personalized, tailored supplement service from a company that I trusted who understood my limitations in what I can and cannot take.

“They accidentally sent a blended supplement to me that contained [a] banned substance called DHEA (which is prohibited at all times under the UFC anti-doping policy).

“Only after I consumed it was its ingredients brought to my attention.”
