BJ Penn has issued a statement after being removed from UFC 199 following a violation of the U.S Anti-Doping Agency. The UFC announced on Monday that Penn had disclosed to the USADA that he had been using an IV while training and that it was a violation of the policy thus Penn was given a provisional suspension and pulled from the UFC 199 event.

On Monday evening Penn issued a statement via his official website to get his side of the story out:

“I voluntarily disclosed to USADA that during a non-fight period that I had an IV administered under the care of a doctor.

“The rule for IV usage had changed since my last fight in the UFC and was unaware of the change and voluntarily disclosed the information to USADA. I had no idea that IV use was banned 365 days a year.

“At no time in my career in martial arts have I ever doped and anticipate all test results from USADA will come back clean and will be working with the UFC to get the matter cleared up and return to fight as soon as possible.”

The use of IVs for purposes of re-hydration has been banned during any time of year by the USADA. Penn had stated that the was unaware of the rule change since his last bout with the UFC. His last bout was back in 2014 against Frankie Edgar. The UFC’s partnership with the USADA began in July of 2015 but the IV ban was not put into place until October of the same year.

As of this writing the full terms and length of Penn’s suspension has yet to be announced.

Penn is the latest fighter to found in violation of the USADA joining Yoel Romero, Lyoto Machida, and Frank Mir.
