RIO DE JANEIRO (AFP) - Russian long jumper Darya Klishina bowed out of the Olympics on Wednesday after failing to make it past the opening rounds of the women's final.

Klishina, who was only allowed into the Games after winning a last-ditch case before the Court of Arbitration for Sport (CAS), could only manage a longest effort of 6.63m.

That left the 25-year-old languishing in ninth place overall, and outside the top eight who advance to the final three rounds of jumping.

It completed a rollercoaster few weeks for Klishina, the only Russian track and field athlete in Rio to escape a blanket ban imposed by the International Association of Athletics Federations (IAAF).

The IAAF had approved Klishina but then excluded her on Friday after receiving new information about her doping samples.

The 25-year-old former European indoor champion had been allowed into Rio because she is based in the United States and underwent regular international doping tests.

After a day of hearings on Sunday, the CAS special anti-doping tribunal announced in the early hours of Monday that Klishina's appeal had succeeded and she "remained eligible to compete in the Olympic Games in Rio."
