Belgian cyclist Johan Sermon has
been found dead from apparent heart failure in his sleep.
The death of the 21-year-old, an under-23 rider with the Daikin team, emerged just hours after Italian cycling star Marco Pantani was also found dead.
A Belgian radio station reported that Sermon's mother found his body on Friday morning.
He had apparently gone to bed early on Thursday to prepare for an eight-hour training ride.
Police were investigating Sermon's death.
Sermon's team manager and former president of the Belgian cycling
federation, Ernest De Vuyst, said the cyclist had recently
undergone a complete cardiovascular check up.
But he added that the cause of death appeared to be heart failure.
"Doping appears to me to be excluded," De Vuyst was quoted as saying.
