ASTANA, Kazakhstan -- Kazakhstan says three medalists are among six of its athletes disqualified from previous Olympics over doping.The countrys national Olympic committee said in a statement that weightlifters Irina Nekrasova and Maria Grabovetskaya, who won silver and bronze medals, respectively, and bronze-medal-winning wrestler Asset Mambetov were retroactively disqualified following retests of drug-test samples they gave at the 2008 Beijing Games.The Kazakhstan Olympic committee said it had received confirmation from the International Olympic Committee that traces of banned substances were found in the athletes samples.The International Weightlifting Federation has previously said the Grabovetskaya and Nekrasova cases concerned various anabolic steroids, with Grabovetskaya testing positive for three banned substances in a single sample. Wrestling authorities have not said what was found in Mambetovs sample.Grabovetskaya and Mambetov were quoted in Kazakh media as saying they will refuse to return their medals because they dont consider themselves guilty of doping.There are also retrospective disqualifications from the 2008 Games for weightlifters Vladimir Sedov and Maiya Maneza, while weightlifter Almas Uteshov has been scratched from the 2012 Olympics. Those rulings do not affect medals.Kazakhstan has one of the worst records of any country in the retests carried out this year by the IOC, having already been stripped of three gold medals last month in earlier doping cases.The retesting program has led to at least 98 positive tests from the 2008 and 2012 Olympics, many of them down to recent advances in techniques for detecting steroids.

John Tavares, Thomas Vanek and Kyle Okposo were also being counted on to slow down sizzling Rangers forward Rick Nash. That plan didnt go so well early. Chelsea came from behind to secure a 3-1 victory over Manchester City at the Eithad in Saturdays early kick-off.A well-contested first half saw few chances for either side, but it was City who broke the deadlock on the stroke of halftime. Gary Cahill inadvertently sent the ball into his own net following Jesus Navas drilled cross, an unfortunate blemish in an otherwise impressive performance from the Chelsea defender.The tempo was raised in the second half, with City missing two opportunities to widen the gap early on. Sergio Agueros effort was hacked off the line by Cahill moments before Kevin De Bruyne missed a sitter from point-blank range.The hosts were made to pay as Diego Costa raced through on goal to beat Claudio Bravo shortly aftter.dddddddddddd From there, Chelsea outshone the Citizens, frequently causing problems on the break.
