Overall leader Remco Evenepoel abandoned the Giro d'Italia on Sunday after testing positive for COVID-19, the Belgian rider said on Sunday.
"It is with a heavy heart that I have to announce that I will be leaving the Giro d'Italia due to COVID-19 after taking a routine test, which unfortunately was positive," Evenepoel, who had regained the Maglia Rosa by winning Sunday's individual time trial, said in a statement.
The new race leader is Britain's Geraint Thomas.
