Russian tennis star Maria Sharapova admits, at an emotional press conference, to having tested positive for a banned medical substance and hints that she will be taking a brief time-out; many of her sponsors and endorsers, especially Nike, announce they are withdrawing their deals.
Unless there is more to come - other substances and stuff - I feel there's a bit of an over-reaction in this. The drug she admitted to has only been on the watch-out list since the beginning of this year (it was on some kind of pre-screening list for a year longer) and it's being used in perfectly legit ways for blood conditions in connection with some diseases. Sharapova claims to have had sensible medical reasons - nothing to do with her sport - for being prescribed the drug over the last ten years, and it doesn't sound like something she would pull out of thin air. Of course athletes are sometimes not allowed to use the same medicines as the rest of us, precisely because of their integrity as competitive athletes, but this substance wasn't even listed until very recently.
Plainly the world of sports is very much on edge over doping because of some recent scandals and failures of anti-doping control, but I really don't think one should jump to the cpnclusion that "she's been doped all along, just another one of them and hey, you know she's a Russian!"
