Kleber Da Silva Ramos had failed the test before the road race and has now accepted a suspension.
A Brazilian cyclist who tested positive for EPO CERA in the week before the Rio Olympics road race has accepted his suspension on a voluntary basis.
Kleber Da Silva Ramos tested positive for the banned substance on July 31 but took part in the road race, though he failed to finish.
He was provisionally suspended by the UCI six days after the race and the Anti-doping Division of the Court of Arbitration for Sport has announced that he accepted his suspension without the need of a hearing.
It means that he is officially disqualified from the Games and the sanction is now referred to the UCI.
The 30-year-old is currently registered with the Brazilian Pro-Continental team Funvic Brasilinvest-São José dos Campos team; his most notable result was when he won a stage of the Tour de San Luis in 2015.
A Chinese swimmer, Xinyi Chen, has also been disqualified from the Olympics and provisionally suspended.
