Suspended NASCAR driver AJ Allmendinger is scheduled to have a secondary sample tested next Tuesday, which should confirm or overturn a positive test he said was caused by a stimulant he didn't take knowingly. Allmendinger was pulled from the Coke Zero 400 at Daytona hours before the July 7 race and informed of a positive drug test result. NASCAR does not release the cause of the positive result. He requested his "B" sample be tested with his own toxicologist present. Allmendinger is expected to receive that clearance this week for the July 24 test. Should the secondary sample produce a negative test result, Allmendinger would be cleared to return to the No. 22 Dodge immediately according to Penske Racing owner Roger Penske. NASCAR has said it would reinstate his license immediately.
