The Movistar team said in a statement the 39-year-old racer had not
recovered in time for the May 11 start of the Giro after a training fall
in April that left him with bruising to the base of his spine.
"The world champion will be resting without risking his recovery and
will get back to normal in the coming weeks," the statement said.
Valverde, Giro winner in 2016, said he was sorry to miss a "great
test" like the Giro but told his social media followers he would be 100
percent ready for the rest of the year.
