SOCHI, Russia -- A Ukrainian cross-country skier has failed a doping test, her countrys Olympic committee said Saturday. It is the third positive result of the Sochi Games. Marina Lisogor tested positive for trimetazidine, which is classified as a "specified stimulant" on the World Anti-Doping Agencys prohibited list. Specified substances are considered more susceptible to inadvertent use and can carry reduced penalties. The 30-year-old Lisogor competed in two cross-country events in Sochi, finishing far out of the medals. According to the Ukrainian Olympic Committee, Lisogor said she did not knowingly take a banned substance. Lisogors failed drug test follows those of German biathlete Evi Sachenbacher-Stehle and Italian bobsledder William Frullani. All three drug-test failures are tied to stimulants. The IOC is conducting 2,453 drug tests in Sochi, a record for the Winter Games. The Olympic body also stores Olympic doping samples for 10 years to allow for retesting when new methods become available. Sachenbacher-Stehle, a former two-time Olympic gold medallist , tested positive for methylhexanamine in both samples. The German Olympic Committee said she was being sent home. She blamed a nutritional supplement and said she had never knowingly taken performance-enhancing drugs. "I am going through the worst nightmare that you can imagine because I am unable to explain at all how there could be a positive test," she said Friday. Frullani was ejected from the games after testing positive for dimetylpentylamine. Frullani, who had not competed yet, asked for a backup test that confirmed the result. The Italian Olympic Committee told The Associated Press it believed Frullani, a former decathlete, bought the stimulant on the Internet from the United States since it is not available in Italy.

Like I said, its not appropriate for me to talk about. I cant do that, Grigson said Friday when asked if the Colts notified the league about a potential deflation problem. Its in the leagues hands. Im sorry.Grigson spoke shortly before the NFL said that evidence shows the Patriots used underinflated footballs during the first half of the game. The league said it wants to find out whether deliberate action was to blame, but provided no timetable for doing so.Underinflated balls in theory could provide an advantage because they would be easier to throw and catch. Under league rules, each team provides balls for use on offence. The balls used by the Patriots were properly inflated for the second half and remained properly inflated after the game, the NFL said.There have been various reports as to how league officials became aware of the situation and whether Indianapolis tipped them off. Nobody in the Colts organization has confirmed those details.Last week, Indianapolis coach Chuck Pagano said he had spoken to the Ravens staff and NFL officiating chief Dean Blandino about the unusual formation New England used during a divisional-round win over Baltimore. Pagano had worked on John Harbaughs staff in Baltimore before taking the Colts job early in 2012.On Monday, Pagano also acknowledged he had spoken with the refs before kickoff against New England, though he did not say whether the air pressure in the footballs came up during the discussion.New England coach Bill Belichick and quarterback Tom Brady have said they didnt know what happened and that they were waiting for the league to complete its investigation. Apparently, so is everyone else.Colts linebackeer DQwell Jackson told reporters Thursday at the Pro Bowl that he gave the ball he intercepted to an equipment manager and that he noticed no difference than other game balls.dddddddddddd. Jackson said he still hasnt gotten the ball back.And Grigson wanted nothing to do with the story.Before we get started, let me cut you off at the pass. Its obviously, like Ive told all you guys, its in the leagues hands, he said as he began the annual post-season news conference. Thats where were at right now.Grigson did shed some light on other topics, though.He confirmed that running back Trent Richardson, the No. 3 overall pick in the 2012 NFL draft, had been suspended two games for personal reasons. Richardson was inactive for the divisional-round win at Denver and last weekends loss against the Patriots. Grigson did not provide further details.As for possible retirements, Grigson said the Colts are not pushing receiver Reggie Wayne or defensive end Cory Redding to make quick decisions and suggested both could still be valuable players next season if they come back.Grigson also said that while the Colts do intend to offer a new contract to Andrew Luck, re-signing the Pro Bowl quarterback is not the top priority this off-season. Lucks original deal runs through 2015, and its a foregone conclusion that the Colts will exercise the fifth-year option to keep him in Indy through at least 2016.So what is Indys biggest off-season priority?Finding a way to get past their biggest nemesis, the Patriots. New England has not only beaten Luck four straight times and eliminated the Colts each of the past two seasons, theyve also rushed for 657 yards and 13 touchdowns in the last three games.I think the (Chicago) Bulls were at that point one time before they started their run. You know, they had to learn to beat the Pistons, the Bad Boys, Grigson said. I think thats where were at. I think we have to figure out, be able to pinpoint those areas because sometimes its not just what you think. Its more than meets the eye.___Online:AP NFL website: www.pro32.ap.org and http://twitter.com/ap_nfl ' ' '
