Russian bobsledder busted for doping wore 'I don't do doping' shirt

You'll never guess who the Russian Bobsled Federation just confirmed has tested positive for a banned substance.

It's bobsled pilot Nadezhda Sergeeva, who recently wore a sweatshirt emblazoned with the words "I don't do doping."

Unlike Russian curler Alexander Krushelnitsky, Sergeeva isn't in danger of having a medal stripped because she finished 12th in her event. But her positive test surely won't help Russia's case for getting reinstated by the IOC, nor sales of that sweatshirt.
