The expert opinion was given by Professor Christiane Ayotte from Canada who was presented by the World Anti-Doping Agency. Narsingh's urine sample taken out-of competition on June 25 was found to contain metabolites of methandienone and long term metabolite of methandienone. ”...all in all found the sabotage (s) theory possible, but not probable and certainly not grounded in any real evidence. The panel is conscious that expert evidence offered by Professor Ayotte may be susceptible to qualification by other expert (s). However, the panel has no reason to question the scientific data and/or her expert testimony,” the full award said.
