MOSCOW -- Darya Pishchalnikova could be stripped of the silver medal she won in the discus at the London Olympics and face a lifetime ban following a positive doping test. Russias All Sports agency said Pishchalnikova tested positive for the banned substance Oxandrolone in a reanalysis of a sample taken in an out-of-competition control last May. The original test was found negative, but her sample was checked again months later based on a more advanced testing method introduced by the World Anti-Doping Agency. All Sports said the retest showed the presence of Oxandrolone in Pishchalnikovas "A" sample. Testing of the backup "B" sample on Nov. 20 also came back positive. The positive test means Pishchalnikova could be retroactively disqualified from the London Games, where she finished second behind Croatias Sandra Perkovic. If the Russian is stripped of her medal, the silver will go to Li Yanfeng of China and the bronze to Cubas Yareli Barriosnikova. It is Pishchalnikovas second doping violation in five years, meaning she faces a lifetime ban if found guilty. She was among seven female Russian athletes found guilty of manipulating drug samples before the 2008 Beijing Olympics, and served a ban of two years and nine months. Pishchalnikova would be the third athlete from the London Games to lose a medal because of doping. Nadzeya Ostapchuk of Belarus was stripped of gold in the womens shot put after testing positive for the steroid metenolone. Last month, the IOC stripped Uzbekistan wrestler Soslan Tigiev of his bronze in the 74-kilogram class after a positive test for the stimulant methylhexaneamine. wholesale jerseys china .

His old friend clobbered him. Otherwise, it was Linsanity all over again at Madison Square Garden. Jeremy Lin had 22 points and eight assists in his return to New York, leading the Houston Rockets to a 109-96 victory Monday night that ended the Knicks 10-game home winning streak to open the season. Cheered then jeered, and later floored by Tyson Chandlers flagrant foul, Lin added another masterpiece to the ones he put together last season during the height of his memorable run. No longer the fan favourite he was when wearing the home uniform, Lin got a mixed reception when he left the game with 2:25 remaining and the Rockets leading by 16. "It was a lot of fun playing out there and I think our team, we took a step in the right direction," Lin said. "And for me, it was great to be back and it was a lot of fun to play on that court again." James Harden had 28 points and 10 rebounds for the Rockets, who blew out the Knicks for the second time this season. They have won the last seven meetings, including a 131-103 rout in Houston on Nov. 23. Rookie Chris Copeland scored a career-high 29 points for the Knicks, who played without leading scorer Carmelo Anthony and had their four-game winning streak snapped. They fell to 18-6, matching the record they finished last season with under Mike Woodson. Woodsons team decided not to match Houstons contract offer to Lin, and nobody could argue when Raymond Felton, Jason Kidd and Pablo Prigioni led the Knicks to the best record in the Eastern Conference with a team that led the NBA in fewest turnovers. But Lin was the best point guard on the floor, just as he so often was during his dazzling run last winter, when the NBAs first American-born player of Chinese or Taiwanese descent went from undrafted benchwarmer to the biggest story in basketball. "He had a good game, without a doubt," Felton said. "I never talked junk about Jeremy Lin. Anything I said about Jeremy, I felt like he deserved anything. He deserved everything he got. He had a good game. Plain and simple." Felton scored 14 points but shot 7 of 18. Kidd was 2 for 9, and both committed three turnovers. The Rockets outscored the Knicks 54-29 over the middle two quarters, denying New York its first 11-0 start at home since the 1991-92 season. The Knicks trailed by just five midway through the third quarter before the Rockets blew it open with a 15-0 run, with Lin either scoring or assisting on five of their six baskets. His layup opened the run, and he then found Marcus Morris for a layup and a 3-pointer for a 67-55 Houston lead. Lin assisted on the second of Hardens consecutive 3-pointers, then had a steaal and layup that gave Houston a 75-55 cushion.dddddddddddd Lin saw some fans wearing his old jersey, but said he didnt let his mind drift back to last season during the game. "Ive moved on, theyve moved on," he said. "We have good memories, but at the same time were all in a different place now." Lin doubled his scoring average in what he called an up-and-down season so far. "I hope this is the start of a nice run for him, because he works really hard," Rockets coach Kevin McHale said. "Hes a great kid. He deserves it." Anthony decided Monday to give his sprained left ankle a second straight game to recover. The Knicks did get good injury news when Amare Stoudemire, out all season after left knee surgery, was cleared to practice. He will work out with Erie, the Knicks NBA Development League affiliate, when it works out at the Knicks training facility on Tuesday. The Rockets snapped a seven-game road losing streak, their longest since an eight-game skid in 2001-02. A sellout crowd that included swimsuit model Kate Upton -- who was on one fewer Sports Illustrated covers than Lin last February -- gave the Harvard graduate a loud ovation during the introduction of starting lineups. The cheers quickly turned to jeers once the game started, particularly when he made a basket. There were boos when Chandler knocked him to the ground with a shot to the head that resulted in a flagrant foul. Chandler felt it was a clean, hard foul that didnt warrant a flagrant. He and Lin hugged after the game. "He had a good game," Chandler said. "He had a good game the other night. Hes a good player. Hes going to have some nights, but I thought we could have took away a lot of his easy baskets, him and James Harden." J.R. Smith came off the bench to make all five shots and give the Knicks a 31-29 after one. The Rockets scored the first 10 of the second quarter, opening a 39-31 lead on Lins 3-pointer with 9:26 left in the half. Houston scored the final six of the half, turning an eight-point lead into a 56-42 cushion. NOTES: Stoudemire is working out with the D-League team because the Knicks are not expected to do much running at practice Tuesday. They havent held a formal practice since Dec. 4. "It seems strange but we have a stretch right now where were playing every other day and its hard to play a game and then think you can come in and drill these guys," Woodson said. "I like to practice, thats where I feel like you learn a lot and stay sharp in terms of your defensive rotations, but I cant run them in practice and expect them to come back and play the next day and then practice again. Theres just too many games coming at us right now." ' ' '
