AJ Allmendinger will be replaced by Sam Hornish Jr. at the upcoming Daytona race after failing a random NASCAR drug test.

Allmendinger was tested during the Kentucky race weekend and his “A” sample tested positive. The driver has the right to request his “B” sample to be tested within 72 hours. For now, he will be temporarily suspended and NASCAR officials didn’t elaborate as to what triggered the failure in the drug test.

“NASCAR has a strict drug testing program that Penske Racing fully supports,” said Allmendinger’s Penske team in a statement. “Penske Racing will work with NASCAR through this process and its next steps. Sam Hornish Jr. will drive the No. 22 car in tonight’s Coke Zero 400.”

Hornish Jr. was contacted to hop into the number-22 Shell Dodge and had to fly from Charlotte to Daytona with barely two hours notice.

Allmendinger is currently racing in his first season for Penske, replacing Kurt Busch who left the team late last year.
