LAS VEGAS -- Interim UFC light heavyweight champion Jon Jones has been pulled from his title-unification bout against Daniel Cormier at UFC 200 on Saturday, after the U.S. Anti-Doping Agency informed Jones of a potential doping violation Wednesday.UFC president Dana White announced the move Wednesday during an impromptu news conference at the MGM Grand.Jones tested positive for a banned substance in an out-of-competition sample taken June 16 by USADA, said Jeff Novitzky, UFCs vice president of athlete health and performance. USADA administers UFCs anti-drug policy.It is important to note that under the UFC anti-doping policy, theres a full, fair legal-review process that is afforded to all athletes before any sanctions are imposed, Novitzky said.Novitzky added that there wasnt time for a full review before the scheduled bout.White said he has not spoken to Jones yet and that he wasnt aware whether the substance in question was a performance-enhancing drug.A heavyweight fight between Brock Lesnar and Mark Hunt will now headline UFC 200, which takes place Saturday at T-Mobile Arena.Jones has the right to appeal any positive test. He has never tested positive for performance-enhancing drugs but did test positive for traces of cocaine before a fight against Cormier in January 2015.Jones also served a suspension from April to October after his involvement in a hit-and-run accident.Under UFCs anti-doping program, which went into effect in July 2015, a positive test for a performance-enhancing drug carries a standard two-year suspension.In an interview with ESPN last week, Jones had expressed hope he could turn his legacy into a positive one.I want to show the world that you can be down but never out, Jones said. I want to be a story where someone risked losing so much but ultimately turned everything around. A lot of times you hear these stories about athletes who ruined their career, and they go away and no one knows what happened to them or theyre bankrupt or they end up in jail. They just ruined a great career. I want to be one of the few stories you hear where I was ruining things but ultimately turned things around and became a hero. Thats my vision for the way my story is going to play out.White said he would like to find Cormier, the defending light heavyweight champion, a new opponent, but that would be difficult because of the timing.When you have the biggest, baddest fight card ever assembled, you know, it doesnt sting as bad when you lose a fight, White said. But it stings real bad for Daniel Cormier. This is devastating to him, his family, and Id like for him to fight another guy.Cormier appeared next to White during the news conference.Ive trained hard and long, Cormier said. If anybody would fight, I would fight. Why not? I understand the difficult task it would be to find me a fight on two days. Im willing to fight up, put on some weight, 225, 220 [pounds]. Ill fight. It doesnt matter. I just cant fight a really big guy, because Ive been shrinking my body.Cormier said he would put in the effort and would accept a new fight if UFC could find one that made sense.Ive worked really hard to prepare for this, Cormier said. You take care of what you need to take care of. Thats what I did. More than anything, its really disappointing.Cormier said having USADA as UFCs partner in the administration of drug testing changes a lot of things and that UFC made a conscious decision to bring in USADA.They didnt have to do this, Cormier said. They decided to clean up the sport. Youre going to have casualties.Cormier said he got a bad feeling in the pit of his stomach when White texted him Wednesday, asking him whether he could make it to the news conference.This guy always gives me good news, Cormier said of White. You know, this guy calls you with a seven-figure check -- Dude, youre rich now -- you know, he calls you with good news. And the mood didnt feel very good. It was scary. So I came here, and I was actually early. Its probably the first time Ive ever been early. I needed to know. But hes usually the good-news guy. And today he had to give me some pretty bad news.Information from ESPN senior writer Arash Markazi and The Associated Press was used in this report. Cheap Nets Jerseys .

Sydney AFL coach John Longmire knows better than most the qualities that make his Fremantle counterpart Ross Lyon one of the best in their trade.Longmire and Lyon each served an apprenticeship as assistant coaches at Sydney under Paul Roos before getting a crack at a head coaching job.Both are now among the most respected mentors in the AFL business.Longmire succeeded Roos at Sydney, steering them to a premiership in 2012 and another grand final in 2014 and almost certainly now to a sixth finals appearance in as many seasons.Lyon, who was also an assistant coach at Richmond and Carlton before joining Sydney, will miss out on the finals this year for just the second time in ten seasons as a head coach.The other time was in his first year at St Kilda, but he subsequently coached in four grand finals across two clubs.Hes a fantastic fellow, I know what hes like as a coach, said Longmire, whose side plays Fremantle in Perth on Sunday.Hes a fierce competitor and so professional in his attitude.I also had the pleasure of rooming with him a few timees when we had a couple of interesting trips.ddddddddddddParticularly trying to get to sleep at night at different times when we were trying to scout opposition teams.He spent a fair bit of time here at the Swans and hes just a fantastic coach and I really enjoy his company.But Im sure we wont be enjoying each others company this week.Although Freo have struggled this year, Longmire is preparing for a high pressure game from a Dockers side intent on marking Matthew Pavlichs 350th game with a win.When you come up against a Ross Lyon coached team you know what you are going to get, Longmire said.Generally its a pretty competitive disciplined outfit and I expect it will be no different this week.They do pressure hard around the ball, they are very disciplined in what they do with and without the ball.They get Matty Pavlich back in the team, so theres some massive pluses for them and thats a terrific challenge for us.
