"Further checks will be carried out over the next few days, right up until the day before the team's departure to the European Championships on Sunday."
Ganna enjoyed a memorable Giro d’Italia for Ineos Grenadiers, claiming four of their seven stage wins in Italy.
The 24-year-old, competing at his maiden Grand Tour, won all three individual time trials, secured a memorable victory from the breakaway on Stage 5 and played domestique to Tao Geoghegan Hart’s unlikely general classification success.
