Paris - UCI president Pat McQuaid says it won't be rushing the investigation into whether Alberto Contador took performance enhancing drugs to win his third Tour de France this year.
Speaking to reporters at the 2011 Tour's route presentation on Tuesday, McQuaid says cycling's governing body is closely working on the case with the World Anti-Doping Agency and is unable to say when the investigation will end.
McQuaid says "it's a very important case and we need to be completely sure before a decision is taken."
Contador has been provisionally suspended for a positive doping test at the 2010 Tour, which he won. The 27-year-old Spaniard claimed that the traces of the banned drug clenbuterol in his sample came from contaminated steak.
