Team owner Roger Penske told radio interviewers on Tuesday that, "We're standing behind him until we understand the results," adding: "I'm hoping that the second test will find him clean and we can move on from this situation."
It has already been confirmed that Hornish will continue to substitute for Allmendinger at this weekend's race in New Hampshire, while tests are conducted on a second 'B' urine sample taken at the same time as the first, on June 29 at Kentucky Speedway. The 'B' sample is intended to ensure there has been no mixup or mistake in the original result, and to allow the driver and his legal and medical representatives to observe the testing process.
The exact timing of when this new test at Aegis Sciences Corporation in Nashville, Tenn. will take place is not yet known: "As of this morning, we have not been given notice of when the testing of the 'B' sample will take place," said Ragan.
Allmendinger's suspension remains temporary pending the 'B' sample results. A negative result would allow him to return to competition, while a second positive result would see him put on indefinite suspension. That would last until such time as he completed a mandatory bespoke 'Road to Recovery' program, unless he was able to persuade NASCAR's medical review officer that there is an alternative acceptable explanation for the result.
The first NASCAR driver to test positive under the new random drug testing system was Jeremy Mayfield in 2009. He denied using methamphetamine and said that the positive result was due to a combination of an over-the-counter allergy medication together with a prescription drug for attention deficit disorder, but he lost his appeal and remains on suspension to this day.
