British rider Simon Yates has withdrawn from the Giro d'Italia after testing positive for COVID-19.
Yates' Australian team, Mitchelton-Scott, revealed the rider had been tested after experiencing "very mild symptoms" following Friday's seventh stage of the race.
That rapid check and a follow-up test both returned positive results.
A team statement read: "The 28-year-old was isolated in his single room during the process and is being safely transported by organised ambulance for a period of quarantine where the team can offer its best possible care. His symptoms remain very mild."
They added that all other team riders and staff have since tested negative and will continue to be monitored.
Team doctor Matteo Beltemacchi told the team's website, greenedgecycling.com: "Simon displayed a very mild temperature on Friday evening during our routine temperature checks, which have been completed three times per day during the course of the Giro d'Italia.
"Following the team's Racesafe COVID-19 policy, he was isolated in his room and we immediately requested a rapid test using the services offering by the RCS, which has returned positive.
"All other riders and staff have returned negative results and have been cleared to continue the race, but as a precautionary measure we will monitor the situation closely and undergo further testing in the coming days."
