Three-time Indianapolis 500 winner Helio Castroneves will race for Arrow McLaren SP at the INDYCAR Harvest GP presented by GMR after Oliver Askew was forced to stand down from the doubleheader at Indianapolis Motor Speedway after being declared not fit to drive by the INDYCAR Medical Team.

“This was an incredibly tough call but I have to follow the advice of the INDYCAR Medical Team and my doctors. My priority right now is focusing on my health,” Askew said. “Despite not being in the car, I will be at the Indianapolis Motor Speedway for the Harvest GP, giving whatever insight and support to Arrow McLaren SP that I can.”

Following the INDYCAR race at Mid-Ohio, Askew reported a balance and coordination issue, which triggered an examination from the INDYCAR Medical Team. As a result, Askew is not medically cleared to race and is subject to INDYCAR’s Return to Racing Protocol.

“The welfare of Oliver, our team members and fellow competitors is paramount,” said Arrow McLaren SP co-owner Sam Schmidt. “We therefore support Oliver and the decision of INDYCAR. Withdrawing to focus on his health and recovery is the right thing to do.”

Castroneves will join Pato O’Ward, driver of the No. 5 Arrow McLaren SP Chevrolet, to complete the team’s driver lineup in Indianapolis.

“First and foremost, we wish Oliver the best and that he is able to take time to recover,” said Helio. “I look forward to getting back on track and helping to build on the great progress that Arrow McLaren SP has made this year.”
