BUSSETO, Italy (AP) - Tour de France champion Bradley Wiggins and defending champion Ryder Hesjedal have both withdrawn from the Giro d'Italia before the start of Friday's 13th stage.
Team Sky says Wiggins made his decision on the advice of the team physician because of "a worsening chest infection."
Sky general manager Dave Brailsford says "he wanted to continue but he is simply unable to do so on medical grounds."
Wiggins struggled throughout the Giro, both on rainy descents and on steep climbs. He lost more than three minutes in Thursday's rainy stage and leaves the race in 13th place, 5 minutes, 22 seconds behind overall leader Vincenzo Nibali.
The Garmin-Sharp team says Hesjedal, who was more than 32 minutes behind in 38th, withdrew because of a "deteriorating physical condition."
