Italian team Vini Zabù has been suspended after a co-driver tested positive for doping, the International Cycling Union said on Tuesday.
Teams with two 12-month doping cases may be banned from competing for 15 to 45 days, possibly excluding the Giro d’Italia team. The three-week competition in Italy starts on May 8.
The UCI said Matteo De Bonis has been suspended pending a disciplinary case after a positive test for blood-raising hormone EPO in a sample taken on February 16.
De Bonis was referred for testing during training by the Lausanne-based International Testing Agency, the UCI said.
Vini Zabù also had a double-positive test for rider Matteo Spreafico for last year’s trial drug ostarine at the Giro d’Italia in October.
The UCI said it would “soon refer the matter to a disciplinary committee, which will decide in time”.
