According to AJ Allmendinger's business manager he tested positive for a stimulant that caused NASCAR to place him on temporary suspension.

Tara Ragan issued a statement on Wednesday outlining what has transpired since Allmendinger failed NASCAR's substance abuse policy test during the Kentucky race weekend.

"A.J. tested positive for a stimulant. He has no idea why the first test was positive, and he has never knowingly taken any prohibited substance," Ragan said. "A.J. is collecting his medicines and supplements for testing to determine whether an over-the-counter product caused his positive test."

According to Ragan, Allmendinger has requested a test of the "B" sample taken. However results of that test may not be known for up to five days.

If that sample matches the positive initial sample, Allmendinger's suspension would be extended indefinitely until he completes NASCAR's "Road to Recovery" treatment program.

"We will have the opportunity to review all of the scientific data surrounding the test following the 'B' sample test," Ragan said. "But our understanding is that AJ's test was slightly above the threshold."

Sam Hornish Jr. will replace Allmendinger in the No. 22 Dodge for the second consecutive week this wekend in New Hampshire.
