SOCHI, Russia -- An unidentified German athlete has failed a drug test in the first announced doping case of the Sochi Olympics. Schuhe Kaufen Schweiz . The German Olympic Committee said Friday it had been notified by the IOC late Thursday that one of its athletes had tested positive on an "A" sample. The backup "B" sample will be analyzed Friday, the German committee said. The Germans did not name the athlete, the sport or the substance involved. Olympic athletes face formal doping charges if both samples are positive. Its rare for a "B" sample to contradict the original "A" finding. The International Olympic Committee would not confirm or deny the positive test, staying in line with its procedures on any doping investigations. "I wont comment on whether a process is even underway," IOC spokesman Mark Adams told The Associated Press. Any athlete found guilty of a doping violation faces disqualification and removal of results and medals. Germany has 16 medals so far in Sochi, including eight golds. Stefan Schwarzbach, the German team spokesman for cross-country and biathlon, said he wasnt allowed to comment on whether the test involved those events or another sport. "All I can say is, we have a positive A sample (somewhere on the German Olympic team)," he said. "But as long as we dont have a positive B sample, we are not allowed to talk about that." The IOC is conducting 2,453 drug tests in Sochi, a record for the Winter Games. The majority of tests are in strength and endurance sports, notably cross-country skiing and biathlon, events where the use of EPO and other blood-boosting drugs can aid stamina. The IOC also stores Olympic doping samples to allow for retesting when new methods become available. The storage period has been extended from eight to 10 years under the next World Anti-Doping Code. Arne Ljungqvist, chairman of the IOC medical commission, said last weekend that he was not surprised there had been no doping cases until then. "Its expected that people dont cheat and those who do are not here," Ljungqvist said, noting that only one positive case was recorded at the 2010 Vancouver Games. A Russian biathlete, Irina Starykh, withdrew from the Sochi Olympics because she failed a doping test before the games.

Cristiano Ronaldo put Madrid in charge with his league-leading 27th goal of the season in the 14th minute, but Sevilla striker Carlos Bacca scored twice, in the 19th and 73rd, to complete the comeback. Madrids loss at the Sanchez Pizjuan Stadium came four days after it squandered a chance to effectively end Barcelonas title defence, with Lionel Messi out-dueling Ronaldo by scoring a hat trick for a thrilling 4-3 win in the Spanish capital. These consecutive losses came after Carlo Ancelottis side had gone undefeated for 31 straight matches. "We have to keep working, fighting and ask our fans for forgiveness," said Madrid full back Marcelo. "Its tough to do what we did, to keep winning for so many games. We have lost two games. They arent more important, but they are critical. Now everything is much more difficult." Diego Costas second-half header gave Atletico a 1-0 victory at home over Granada as it moved three points clear of Madrid with eight rounds remaining. Lionel Messi and Neymar helped Barcelona stay one point behind Atletico as it rose into second place, but the 3-0 win over Celta Vigo came at the cost of goalkeeper Victor Valdes tearing a right knee ligament. "I am happy for the goals and for having won the other day at the Santiago Bernabeu," said Neymar. "(But) the victory is sad because of Valdes injury." Ronaldo struck first at Sanchez Pizjuan Stadium when his free kick took a deflection off the arm of Bacca, catching goalkeeper Antonio "Beto" Bastos out of position and helpless as he watched the ball float into his net. But Bacca equalized from Jose Antonio Reyes pass after Xabi Alonso had lost possession. Madrid then wasted several chances, and Sevilla tilted the match in its favour in the second half when Ivan Rakitic used a superb control of aa pass before playing Bacca clear to beat goalie Diego Lopez for the winner.

Atletico stayed unbeaten at home in league play this season after limiting Granadas attack with its stout defence before Diego Costa turned home Jose Sosas corner kick in the 63rd for his 24th league goal of the season. Earlier at Camp Nou, Valdes right knee buckled after a routine save in the 22nd, and he had to be shuttled off the pitch with his gloved hands covering his face. The club later said he will need surgery, which would rule him out for the season. Neymar netted twice from passes by Alexis Sanchez. The Brazil striker opened the scoring in the sixth minute and struck again in the 67th after Messi recorded his 22nd league goal of the season on the half-hour mark. Celta, coached by former Barcelona player and B-team manager Luis Enrique, never mounted a challenge and its high defensive line proved easy pickings for the Catalan sides passing game. Messi got things rolling when he dribbled at Celtas defence and spotted Alexiss run down the right edge of the area, where he received Messis pass and squared for Neymar to tap home. After Jose Pinto went on to replace the injured Valdes, Messi took Andres Iniestas pass, rounded keeper Yoel Rodriguez and fired the ball inside the upright for his eighth goal in his last four matches. Pain in his left leg kept Iniesta from returning after halftime, but he said he expected to be fit to play at Espanyol on Saturday. The 38-year-old Pinto was tested in the 52nd and was up to the challenge when he made back-to-back reflex saves to turn away Augusto Fernandezs powerful strike and Santi Minas follow-up attempt. He went on to make two more noteworthy saves. Neymar hit a second time from a long pass by Alexis when he managed to slot the ball through two defenders and beyond Rodriguez. Also, Rayo Vallecano beat Osasuna 1-0 thanks to Joaquin Lavirreys 90th-minute penalty for its fourth win in five rounds to edge away from the relegation zone. ' ' '
