Britain’s Tom Pidcock will miss the Milan-San Remo race on Saturday with concussion.
The Ineos Grenadiers rider, who won the Strade Bianche classic earlier this month, crashed out of Sunday’s final stage of the Tirreno-Adriatico.
“This is obviously disappointing for both Tom and team,” said deputy team principal Rod Ellingworth.
“We saw at Strade Bianche the sort of form he’s in and I know how keen he was to carry that into Milan-Sanremo.”
Ellingworth added: “Rider welfare is our first priority and he’ll follow the advice of our medical team to ensure that he’s 100% ready to safely resume his Classics campaign.”
Milan-San Remo is one of five prestigious ‘Monument’ one-day races in cycling along with the Tour of Flanders, Paris-Roubaix, Liege-Bastogne-Liege and Giro di Lombardia.
