MADRID (AP) -- The World Anti-Doping Agency has suspended Spain's accredited lab in Madrid from carrying out doping tests for three months. The suspension comes weeks before Madrid submits its final bid to host the 2020 Summer Olympics.
WADA said Friday the lab may appeal the decision to the Court of Arbitration for Sport within 21 days. The Montreal-based agency said the lab failed to meet requirements but did not elaborate.
Spain's Anti-Doping Agency cited a mix-up of two urine samples in August. It said in a statement one sample was "contaminated by a sample from a different athlete that contained a high concentration of a banned substance."
The statement said no athlete was incorrectly accused of doping and the lab's head of quality control resigned after the suspension.
