BEIJING (AP) — Kamila Valieva was back on the Olympic ice at the Beijing Games for the individual competition. Details of her legal defense in a doping case were revealed only hours earlier. Lawyers for the 15-year-old Russian skater argued contamination from heart medication her grandfather was taking caused her positive test in a sample taken weeks before the Olympics opened. The argument was made at the Court of Arbitration for Sport hearing late Sunday night. It is expected to be part of her defense in the Russian investigation of her doping case. The legal process and final results of Valieva’s Olympic events will likely take several months.
