SAO PAULO — Doctors have ordered IndyCar points leader Helio Castroneves to skip a stock car event in Brazil after he crashed hard in practice.

Castroneves wasn't seriously injured when the brakes on his car malfunctioned and he crashed into a tire barrier on Friday, but doctors said the three-time Indy 500 winner is still too sore to endure the street-circuit race in the city of Ribeirao Preto on Sunday.

Dr. Dino Altmann said Saturday that Castroneves is "not really physically fit to race" and that it would be too painful for him to try.

Castroneves sustained cuts to his shins and had pain in his neck after the head-on crash into a tire barrier, but he said "thankfully tests showed no serious injuries."
