Askew out with concussion

IndyCar rookie Oliver Askew will not compete in next week’s doubleheader at Indianapolis because of concussion-like symptoms that date to his crash in the Indianapolis 500 last month. Arrow McLaren SP will use Helio Castroneves in the No. 7 Chevrolet at Indianapolis. Askew, 23, told The

Associated Press on Thursday he has been experiencing dizziness, sleeping difficulties, irritability, headaches and confusion since he crashed late in the Aug. 23 race. He continued to race and tried to “play through it” until friends and family encouraged him to seek medical treatment. His performance

had been obviously off in the four races since his crash at Indianapolis. Askew, last year’s Indy Lights champion, had finished third and sixth at Iowa — the previous two races before Indianapolis.
