According to CNN.com, "former Olympic 800 meters silver medallist Hezekiel Sepeng has been reinstated after serving a two-year doping ban, Athletics South Africa (ASA) said on Tuesday."
USAToday.com reports that Russian marathoner Lyubov Denisova has been banned for two years "because she tested positive for prostanozol and testosterone." Denisova's agent claims that she "made a mistake while buying vitamins on the Internet with a new computer early this year." Some mistake. That computer must have come loaded with Windows Vista.
