Sam Hornish Jr., who was pressed into service as an emergency replacement for suspended NASCAR Sprint Cup driver A.J. Allmendinger in Saturday night's Coke Zero 400 at Daytona International Speedway, will drive for Allmendinger in the No. 22 Pennzoil Dodge fielded by Penske Racing in Sunday's Lenox Industrial Tools 301 at New Hampshire Motor Speedway.

Penske Racing officials issued the following statement Monday:

"Penske Racing is continuing to work with NASCAR to follow its process and procedures related to the positive drug test that AJ Allmendinger was notified of this past weekend. While this process continues, Sam Hornish Jr. will drive the No. 22 car in this week's Sprint Cup Series race at New Hampshire Motor Speedway."

Hornish, who drives in the Nationwide Series for Penske Racing, was summoned from Charlotte, N.C., to replace Allmendinger after NASCAR officials indefinitely suspended him for testing positive for a banned substance.

Without any practice time in the car, Hornish arrived Daytona, jumped into the No. 22 Dodge, and finished 33d.

Allmendinger will have an opportunity to appeal the positive test result.
