Earlier this week news surfaced that former UFC champion Lyoto Machida had been pulled from his upcoming UFC on FOX 19 scrap against Dan Henderson after admitting to using a banned substance during an out-of-competition drug test.

While Dan Henderson was extremely pissed about the situation, Machida claimed that he was unaware that the substance contained a banned substance. The way top ranked welterweight Matt Brown sees it however, that’s not an excuse.

He spoke on The Great MMA Debate Podcast:

“A guy has to know what he’s putting in his body,” Brown said. “I’ve been on a web search for less than two minutes here and just did Wikipedia and it says the World Anti-Doping Agency lists 7-Keto/DHEA as a prohibited anabolic agent.”

“Ignorance has never been an excuse,” Brown said. “You can’t go 65 (miles-per-hour) down the road and say oh I thought it was a 35 mile-per-hour zone. You still get the fine, you still get the ticket. Ignorance has never been an excuse.”

So far no word yet on how Machida will be punished for the infraction.

Stay tuned for details as they become available.
