A gear failed on Danica Patrick’s Stewart-Haas Racing Chevrolet during NASCAR Sprint Cup practice at Dover International Speedway today, sending driver Jamie McMurray and Patrick’s team owner Tony Stewart into an unprotected hard wall. That’s worrying for Stewart, who is still recovering from a back injury.
Stewart missed the beginning of the season after fracturing his L1 vertebrae in an ATV crash this January. Doctors are still advising him to be careful. Earlier this month, he opted to start at Talladega—a venue known for huge crashes—but hand the car over to Ty Dillon during the first caution.
