PARIS — Bradley Wiggins's Tour de France challenge ended before it even started Friday when the defending champion was ruled out of Team Sky's selection for next month's race because of physical problems. Briton Wiggins withdrew from the Giro d'Italia this month with a chest infection and he has also been struggling with a knee problem, meaning he cannot train properly to defend his title on the Tour, which starts on June 29 in Corsica. “With illness, injury and treatment Brad has gone past the point where he can be ready for the Tour. It's a big loss but, given these circumstances, we won't consider him for selection,” Team Sky principal Dave Brailsford said in a statement. — Reuters
