It seems almost certain that Iban Mayo will miss the Vuelta after being diagnosed with a glandular fPICTURE BY TIM DE WAELE The Euskaltel team have announced that their star rider, Iban Mayo, is almost certain to miss next month's Tour of Spain after being diagnosed with a glandular fever-like virus. Mayo pulled out of the Tour de France last month just before the Alpe d'Huez time trial stage suffering from an unexplained and total lack of form. Although Euskaltel team boss Miguel Madariaga has said there is still a 10 per cent chance of Mayo starting the Vuelta, the likelihood is that the Basque rider's season is over. "Based on the analyses that have been done he can't race, his haematocrit level won't go above 37 per cent, which suggests he has a virus," said Madariaga. In a further statement, Madariaga clarified Mayo's medical status by explaining he had "infectious and acute glandular fever." Mayo has been told by medical staff that the only long-term cure is rest. A later medical statement said that the virus had been incubating within Mayo between his Dauphin victory in June and the start of the Tour in early July. The infection was described as "not serious for the ordinary person" but "more so in the case of an athlete". The infection, it seems, worsened once Mayo began to experience the heavy workload at the Tour. Mayo is still doing low intensity training before undergoing another medical check in early September.
