“As anyone that knows me or follows me on social media is aware, I am an outspoken advocate for keeping MMA clean of PEDs. I was shocked when I was told that I could not fight this weekend,” Sullivan wrote on Facebook. “I did not fail a test. I was pulled from the card due to a natural supplement being on my list of supplements that I voluntarily disclosed to USADA. This supplement has been on my list that I have disclosed to both the UFC and USADA prior to my previous fights.
“I have been tested for PEDs countless times in my career by different testing authorities, including USADA. I have never tested positive for any banned substances.”
Sullivan was slated to face Hector Urbina in a preliminary welterweight bout at the United Center in Chicago on Saturday night. Instead, the five-time Octagon veteran is left with out a fight as USADA investigates his situation.
“I want to thank everyone that supports me,” he wrote. “I plan to do whatever it takes to clear my name. I am confident that my name will be cleared.”
