Former UFC light heavyweight champion, Lyoto Machida has been suspended 18 months by USADA following an incident involving their anti-doping program.
Machida declared the use of a prohibited substance and then subsequently tested positive for the substance, according to an official statement by USADA today.
The substance in question is called 7-keto-dehydroepiandrosterone (DHEA) which is a steroid. Machida included this information on his paperwork during a out-of-competition test on April 8.
According to USADA, Machida, "fully cooperated with the subsequent investigation after advising USADA that he did not realize 7-keto-DHEA was a prohibited substance when he used the product."
Because of this, the possible two-year suspension was reduced to 18 months.
Machida was preparing to fight Dan Henderson at UFC on FOX 19 in April, but was pulled after he admitted use of the product.
The suspension is retroactive to April 8, 2016, so Machida will be eligible to fight again in October 2017.
