Riccò did self-transfuse...

VeloNews has an article saying that a report in Gazzetta dello Sport says an investigation into disgraced cyclist Riccardo Riccò's mysterious collapse earlier this year was indeed due to a self-administered blood transfusion  (Probe reveals Ricco self-transfusion – report).  Having spent this weekend reading David Millar's excellent account of his fall from grace into doping, and his subsequent rehabilitation (Racing Through the Dark: The Fall and Rise of David Millar), it's just so depressing seeing someone who is quite probably a very talented athlete take themself so close to death.
