The United States Anti-Doping Agency (USADA) has notified the UFC of a second failed drug test submitted by former heavyweight champion and WWE star Brock Lesnar.UFC officials were informed Tuesday that Lesnar, 39, failed a fight night drug test at UFC 200 on July 9 in Las Vegas. Results showed the presence of the same unidentified banned substance Lesnar tested positive for on June 28.The substance that Lesnar tested positive for hasnt been officially identified, but a source told ESPN that the flagged substance is clomiphene, the same anti-estrogen blocker for which Jon Jones tested positive.Neither of those test results was available to the promotion on July 9, which is how Lesnar (6-3) was still able to fight Mark Hunt at T-Mobile Arena. Lesnar won the fight via unanimous decision.Lesnar, who is still under contract with the WWE and came out of retirement to face Hunt earlier this month, has not said much on the initial June 28 test. He told The Associated Press last week, We will get to the bottom of this.His appearance at UFC 200 marked Lesnars first professional fight since December 2011. His financial purse, as reported to the Nevada State Athletic Commission (NSAC), was $2.5 million.Under the UFCs anti-doping program, which went into effect in July 2015, results management and adjudication of the case falls to USADA, although Lesnar will also be subject to the jurisdiction of the NSAC. The UFC and NSAC withhold the right to fine and suspend Lesnar, in the result of a confirmed doping violation. Lesnar has not publicly disclosed whether he intends to have his B-samples tested.It is important to note that, under the UFC Anti-Doping Policy, there is a full fair legal review process that is afforded to all athletes before any sanctions are imposed, UFC said in a statement. The Nevada State Athletic Commission also retains jurisdiction over this matter as the sample collection was performed at UFC 200 in Las Vegas.Consistent with all previous potential anti-doping violations, additional information will be provided at the appropriate time as the process moves forward.Hunt (12-11-1) was furious following news of Lesnars first potential doping violation. Late last week, the 42-year-old demanded Lesnars entire paycheck in a social media post. Hunts reported purse was $700,000.Lesnar, a former NCAA wrestling champion and two-time defending UFC champion, had never tested positive for a banned substance before the June 28 out-of-competition test. The UFCs anti-doping program requires any retired fighter be subject to a four-month testing window prior to resuming competition; however, the UFC elected to waive that requirement for Lesnar, whose fight against Hunt was announced one month prior to UFC 200.According to the USADA website, Lesnar submitted eight total samples to the anti-doping agency. USADA official Ryan Madden previously confirmed to ESPN that Lesnar had submitted multiple test samples before June 28 and that each came back clean.When asked about performance-enhancing drugs during an international conference call earlier this month, Lesnar responded: Im a white boy and Im jacked. Deal with it.Pending a successful appeal to the July 9 test, Lesnars victory against Hunt will likely change to a no-contest. Following his successful return at UFC 200, Lesnar had not indicated whether he wished to fight again.Brad Peacock Astros Jersey .

Carlos Lee Astros Jersey . -- The Portland Timbers and Real Salt Lake played to a 0-0 tie Saturday night that left the top of the Western Conference standings unchanged. Jose Cruz Jr. Jersey . Isner, ranked No. 14, won his eighth career singles title and took the title in New Zealand for the second time after his victory in 2010.

He can start Sunday from pole position at the U.S. Grand Prix.Hamilton outgunned his Mercedes rival and teammate on the last lap to grab his first pole position at the Circuit of the Americas, where hes won three times starting from second.I feel amazing, Hamilton said. I could hear the crowd cheering.Hamilton has been a Texas favorite with his three wins in four years and he returned this year facing a 33-point deficit behind Rosberg in the title chase. His fastest lap of 1 minute, 34.999 seconds pushed Rosberg to No. 2.It was a good lap I did. Annoyed when Lewis crossed the line and beat me, said Rosberg, who also threw a jab at Hamiltons season-long troubles getting off the starting line.As weve seen this year, qualifying isnt all important, Rosberg added. From P2 I still have a great chance for tomorrow.Indeed, Hamilton has been bedeviled by poor starts and pole position Sunday could mean little. Hes won only three of the previous eight races this season when he started No. 1.A good start will be critical Sunday. The first sector at the Circuit of the Americas sends the cars up through a 110-foot elevation and into a hard left turn that sends them back downhill. Rosberg admits he struggles with the turn, where Hamilton got the inside line at the start in 2015 and bumped him wide.Its very technical in terms of braking and positioning. Its very difficult, Hamilton said.Hamilton has dominated this track and his win last year clinchhed his second consecutive season championship and third overall.ddddddddddddBut Rosbergs lead is large enough that he can chase down this seasons title without a victory over the final month. Even if Hamilton wins the last four races, Rosberg wins the title with three seconds and a third.But a Rosberg win could crush Hamiltons rally hopes. Rosberg has said all week he wont settle into the safety of second place on Sunday.It would be amazing to win the U.S. Grand Prix, Rosberg said. Ill be focused on that.A win Sunday would make Rosberg just the fourth driver in Formula One history to get 10 in a single season. And it would push him that much closer to matching the 1982 championship won by his father, Keke Rosberg. He would also be in striking distance of the single-season victories record held by Michael Schumacher and Sebastian Vettel.Red Bull flirted with the top spots Saturday when Max Verstappen and Daniel Ricciardo went 1-2 in the morning practice. But neither car was able to challenge the supremacy of Mercedes once qualifying began.Ricciardo, who finished third in Austin in 2014 and won in Malaysia when Hamiltons car didnt finish, hopes he can make another podium. Verstappen will start fourth. Ferraris Kimi Raikkonen and Vettel will start fifth and sixth.Not really close to Mercedes, but we expected them to be very hard to beat, Ricciardo said. Its a good fun circuit, good for overtaking. Well see what happens. ' ' '
