The International Cycling Union has suspended Belarusian rider Kanstantsin Siutsou after he failed a doping test.
Siutsou joined the Bahrain-Merida team last year and won the Tour of Croatia in April. He planned to race in the Giro d'Italia in May but withdrew after fracturing a bone in his neck during training.
The UCI says the 36-year-old Siutsou tested positive for the banned blood-booster EPO on July 31 and has been suspended pending a full hearing.
Bahrain-Merida general manager Brett Copeland says "this behavior is not accepted by our team and further procedures will be taken against the rider."
