Jon Jones appears extremely confident ahead of his upcoming arbitration hearing with the United States Anti-Doping Agency.Jones, 29, is scheduled to become the first UFC athlete to enter arbitration with USADA on Oct. 31 in Los Angeles. He is contesting USADAs sanctions related to a failed drug test earlier this year, which resulted in his removal from UFC 200 on July 9.The UFC was forced to pull Jones from the event just days before, after it was revealed he tested positive for the banned substances clomiphene and letrozole. It marked the first failed drug test of Joness outstanding mixed martial arts career.Jones immediately proclaimed his innocence and has maintained he never knowingly took a banned substance. His attorney, Howard Jacobs, has stated the failed test is the result of Jones taking a legal tainted supplement. USADA has not yet confirmed Jacobss statements.The fact this product was contaminated with the very things he tested positive for tells you all you need to know, Jacobs told ESPN on Tuesday. Youd have to be pretty cynical to say, Well, he must have just gone out and bought something that would provide a ready explanation. Thatd be a lot of guessing which product would come back contaminated with these two substances.This product was tested in open packets, sealed packets, purchased by USADA -- it came back contaminated across the board. Its pretty hard to say this is a made up story.On Monday, Jones took to social media to express his feelings on the situation.Thats right light heavyweight division, Jones wrote on Twitter. This means I got in that a-- fair and square. I heard your interviews. Steroids didnt give me the believe that I am the baddest fm on this planet. It didnt give me the heart to pull off victories in the last minutes of championship fights.Steroids will never give you a high IQ of the game. It wont increase your awareness or your timing. It wont make you more technical. It didnt give me the idea to set my mind to a goal, to follow my dreams and bust my a-- every day in the gym. I know that Ive earned every inch of my success, every match won.Earning this high place in sports gives me the confidence and courage to know that I can do the same in my life. I know that I have something extremely powerful inside of me. I have the power to achieve anything I set my mind to. Knowing this helps me not worry when times get rough, I am more than a conquerer. I have what it takes to win.Based on the substances for which he tested positive, Jones faces a maximum one-year suspension. Since his last fight was scheduled to take place in Las Vegas, Jones is also subject to disciplinary action from the Nevada State Athletic Commission. The NSAC granted Jones a continuance on his hearing last month. He is expected to appear before the commission in November.Jones (22-1) is widely considered the greatest fighter in the world, but his troubled personal life has interfered with his athletic career.The UFC stripped Jones of his 205-pound championship last year, after he was arrested on a hit-and-run charge in Albuquerque, New Mexico. Although he is the first UFC athlete to arbitrate a case, he would not be the first to receive a reduced sentence based on a tainted supplement. UFC athletes Yoel Romero and Tim Means have each successfully argued failed drug tests were the result of tainted supplements and received lesser penalties. Custom Brewers T-shirts .
