The U.S. Anti-Doping Agency on Friday that Colombian Lisban Quintero has accepted a two-year suspension from competition after the former Century Road Club Association rider tested positive for norandrosterone.

The USADA announcement confirms an earlier statement by the CRCA that it had suspended Quintero from the team after learning of a positive test result for the anabolic agents, 19-norandrosterone and 19-noretiocholanolone. The 29-year-old Quintero was tested on May 22 at the Wilmington Grand Prix in Wilmington, Delaware.

Such anabolic agents are prohibited under the USADA Protocol for Olympic Movement Testing and the rules of the UCI, both of which have adopted the World Anti-Doping Code and the World Anti-Doping Agency Prohibited List.

Quintero accepted a two-year period of ineligibility, which began on June 23, 2011, the day he accepted a provisional suspension. As a result of the sanction, Quintero is also disqualified from all competitive results obtained on and subsequent to May 22, 2011, the day his sample was collected, including forfeiture of any medals, points, and prizes.
