Tour de France leader Michael Rasmussen will not compete in either the Olympics or the World Championships after being dropped by the Denmark cycling team in a row over drug testing.

The Danish Cycling Union (DCU) claimed Rasmussen, who rides for the Rabobank team, had been warned three times about failing to inform drug testers of his whereabouts.

Under International Cycling Union (UCI) rules athletes must inform the sport's governing body of their schedule in order for random drug tests to be carried out.

If a rider misses three tests in an 18-month period they will be deemed to have committed a doping violation and will face a two-year ban.

DCU director Jesper Worre said: ‘It has been decided that Michael will no longer be part of the national team.’

He added on Danish TV station DR: ‘We've got information from both the UCI and Anti-Doping Denmark and we know that he received several warnings.

‘It's confidential information.’

Rasmussen responded by claiming he had only received one warning and blamed a postal delay.

‘There must be someone at the top who doesn't wish me well,’ he said.
