Alberto Contador looks set to miss the road race at next month's Rio Olympics after saying on Tuesday that he needed four weeks to recover from injuries sustained on the Tour de France.

The Spaniard, who withdrew from the Tour during Sunday's ninth stage, told a news conference in Madrid that his goal now was to get ready for the Vuelta (Tour of Spain) which starts on 20 August.

The men's Olympic road race will be held on 6 August, almost four weeks after he sustained his injuries in two crashes in the first two stages of the Tour.

"The prospect of the Games is practically discarded," 33-year-old Contador said.

"The goal is to recover for the Vuelta. It is a blow to the morale because the Games were the second big goal of the year and I had to discard them."

Nicholas Roche and Dan Martin, currently in third place at the Tour de France, will form the Ireland team for the event on day one of the Olympics.
