Chase Dietz will wheel the No. 1a Shark Racing entry at the Knoxville Nationals, as its typical pilot, Jacob Allen, continues to take time off from racing.
Shark Racing confirmed Dietz as the substitute driver via Twitter on Wednesday morning.
Allen was previously named on the entry list and was slotted to compete in Wednesday night’s qualifying event at Knoxville Raceway.
Though he ran the most recent World of Outlaws Sprint Car Series events at Weedsport (N.Y.) Speedway and the Ironman 55 at Missouri’s Federated Auto Parts Raceway at I-55, Allen will not be racing the Nationals, opening up a spot for Dietz.
The York, Pa., native has won several 410 sprint car features at half-mile tracks in Pennsylvania, including Williams Grove Speedway and Lincoln Speedway. Dietz has also raced with the Outlaws during their visits to the aforementioned tracks.
He’ll try his luck at the famed half-mile dirt oval in Knoxville, Iowa, starting Wednesday.
