LAUSANNE, Switzerland -- Nine more athletes, including six medal winners, were retroactively disqualified from the 2008 Beijing Olympics on Wednesday after failing retests of their doping samples.The International Olympic Committee announced the decisions in the latest sanctions imposed on athletes whose stored samples came back positive after being retested with improved methods.Four athletes were stripped of silver medals and two of bronze medals in weightlifting, wrestling and womens steeplechase. All six athletes come from former Soviet countries -- Russia, Belarus, Ukraine, Uzbekistan and Kazakhstan -- and all tested positive for steroids.The IOC stores doping samples for 10 years to allow them to be reanalyzed when enhanced techniques become available. The IOC recorded a total of 98 positive cases in recent resting of samples from Beijing and the 2012 London Olympics.Stripped of silver medals Wednesday were freestyle wrestlers Soslan Tigiev of Uzbekistan (66-74 kilogram division) and Taimuraz Tigiyev of Kazakhstan (84-96 kg) and weightlifters Olha Korobka of Ukraine (75 kg) and Andrei Rybakov of Belarus (85 kg).Its the second time Tigiev has been stripped of an Olympic medal for doping. He lost his bronze medal from the 74 kg event at the London Games after failing a drug test.The IOC stripped Beijing bronze medals on Wednesday from Russian steeplechaser Ekaterina Volkova and Belarusian weightlifter Anastasia Novikova (53 kg).The IOC asked the international weightlifting, wrestling and track and field federations to modify the Olympic results and consider any further sanctions against the athletes. Decisions on reallocating the medals have not been finalized.The IOC said all six medalists tested positive for the steroid turinabol. Rybakov and Novikova also tested positive for stanozolol. Both substances are traditional steroids with a history dating back decades. The new IOC tests used a technique that could detect the use of those drugs going back weeks and months, rather than just days.Also disqualified Wednesday were Cubas Wilfredo Martinez, who finished fifth in the mens long jump; Nigerian-born Spaniard Josephine Onyia, who was eliminated in the semifinals of the womens 100-meter hurdles; and weightlifter Sardar Hasanov of Azerbaijan, who competed but did not finish in the mens 62-kg division.The IOC said Hasanov tested positive for turinabol, Martinez for the diuretic and masking agent acetazolamide, and Onyia for the stimulant methylhexanamine.Last week, the IOC announced that Russian weightlifter Apti Aukhadov had been stripped of his silver medal from the London Olympics on Tuesday after testing positive for turinabol and drostanolone.

Gray will be back on duty against Manchester United on Saturday for the first time since September 17, having been banned by the FA for misconduct in relation to comments he made on social media dating back to 2012.The 25-year-old has apologised for the messages, which appeared during his time with non-league Hinckley United, and stressed he was absolutely not homophobic. Sean Dyche believes Burnleys striker Andre Gray should be allowed to move on from his ill-advised social media posts Burnley have condemned the posts but supported their player and now manager Dyche hopes to draw a line under the incident.I dont know what abuse he will get, Dyche said. If you come out, hold your hands up and say thats not me any more, what abuse will you get? Gray sorry for tweets Burnley striker Andre Gray apologises for homophobic tweets Theres no crystal ball for me, hes a young man developing and learning, and theres no guarantees hes going to cope with it in any way, either positive or negative.I think its fair to say his behaviour will be monitored more closely. I dont mind that. I think that comes with the territory a little bit, first of all going into the Premier League as a player and then with an incident thats not to do with football. Highlights: Burnley 2-1 Everton This type of situation, he can only learn from.dddddddddddd Hes got to learn from it, its happened, so you get a sanction for it., you pay your price for want of a better way to put it, and move forward.The ones who dont learn are often the ones who have trouble in the future, and I dont think hes that type, hes trying to move forward.While Dyche is not sure how Gray will be treated by rival fans, or how it will impact his game, he questioned whether footballers should use social media platforms.
