COLORADO SPRINGS, Colo. -- The U.S. Anti-Doping Agency performed 2,156 doping control tests in the third quarter of 2006, resulting in four violations, including the one accepted by sprinter Justin Gatlin.
In August, Gatlin received a maximum eight-year ban resulting from a positive test for testosterone or other steroids -- the second positive doping test of his career. He has until next February to file an appeal in an attempt to shorten the ban.
He avoided a lifetime penalty for his willingness to cooperate with doping authorities on other cases, and because an earlier positive drug test was deemed an honest mistake.
The other violations this quarter included one test for marijuana use, another for diuretics use and an athlete who missed three tests over an 18-month period, according to figures released Wednesday.
Swimmers (348), cyclists (285) and track and field athletes (263) were the most-tested groups.
