Brad Keselowski won't run in Saturday's NASCAR Nationwide race in Iowa following a head-on crash into a wall at Road Atlanta on Wednesday.
Penske Racing says Thursday that Parker Kligerman will drive the No. 22 Dodge in Friday's practice sessions, but Sam Hornish, Jr., will run both qualifying and the race.
Keselowski crashed during a testing run in Atlanta. He walked from the car and was taken to the hospital for precautionary reasons. Penske says it will evaluate Keselowski's condition and provide information when it becomes known.
Keselowski won the inaugural Nationwide race at Iowa Speedway in 2009.
