The International Olympic Committee announced Sunday that Colombian runner Diego Palomeque Echavarria's positive drug test has been confirmed.

After testing positive for testosterone, Echavarria was provisionally suspended on Aug. 4, preventing him from running that morning in heats for the men's 400 meters. The suspension became official after analysis of the "B" sample confirmed the initial test.

The IOC said in statement Sunday that they also requested the Colombian Olympic Committee to "investigate the matter of the injections administered to the athlete by his coach, Raul Diaz Quejada, and to take any appropriate sanctions or measures within its own competence."

The statement also said that, "the IOC reserves its right to consider possible further sanctions or measures in relation to this matter."
