Jack Hawksworth hit the wall at Pocono so hard that he hurt his heart.

Hawksworth hopes the wreck won't halt the momentum of his promising rookie season in IndyCar.

Hawksworth arrived for pre-race preparations at Iowa Speedway on Thursday, just four days after being released from the hospital. Hawksworth missed last weekend's race at Pocono Raceway after a nasty crash during a practice run.

The 23-year-old native of England was diagnosed with a myocardial contusion — more commonly known as a bruised heart — but he's since been cleared to run on Saturday.
