LONG POND, Pa. (AP) -- Jack Hawksworth missed the IndyCar race Sunday at Pocono because of a heart contusion.
Hawksworth was injured Saturday in an accident during the second practice session.
He was evaluated and released from the infield care center. Hawksworth stayed overnight for observation at a hospital and was released Sunday.
Hawksworth will be re-evaluated by the IndyCar medical team Tuesday before being cleared to drive next week at Iowa Speedway.
The 23-year driver from Bradford, England, was coming off a season-best third-place finish at Houston. After his accident in practice, he did not make a qualifying attempt.
''Just a little bit sore. I think I'll be cleared to drive, so that's not a problem,'' he said.
