Undefeated heavyweight Giacomo Lemos was removed from UFC 240 days before his fight with fellow newcomer Tanner Boser after his USADA test came back positive for a banned substance.

A day after being informed of the failure, Lemos (6-0) released a statement to MMA Fighting maintaining his innocence and saying he will get his supplements tested to find out how he popped for drostanolone, an anabolic steroid.

Read Lemos’ statement below.

“I still don’t really know what happened, but we suspect that an anti-inflammatory injection I took on my last fight in Seoul [on April 8], before I had a contract with the UFC, was contaminated with this substance, a substance that stays longer in your body.

“I got confirmation that I was going to fight in the UFC on six weeks’ notice. My test was done on July 9, and unfortunately the result came back two days before my debut. We’re also investigating all supplements I took since then and we’ll get them analyzed as well to check for a possible contamination, besides asking for the B sample to be tested because the amount was so low it would mean no benefit in this fight.

“I want to make clear that I’m completely against any form of doping. I’ve was always been a clean athlete and competed in many different sports, being drug tested before, and never tested positive for anything.

“My goal is to continue in the UFC proving my innocence in this case because I know I have what it takes to fight for the belt one day.”
