World Champion Alessandro Ballan's participation in the Monte Paschi Eroica on Saturday is in doubt after he fell ill. Ballan complained of a stomach ache and curtailed his training to return early to his Lampre-NGC team's hotel in Asciano, Italy, on Friday.
Doctor Andreazzoli subsequently visited the Ballan and diagnosed him with a virus, which is also causing a fever.
Ballan, along with his managers and the team's medical staff, will decide on Saturday morning whether he will start the race.
