Ahmard Hall: Adderall caused test, ban

NASHVILLE, Tenn. -- Tennessee fullback Ahmard Hall says Adderall borrowed from a friend to help him drive home to Texas caused his positive drug test and four-game suspension under the NFL's policy on performance-enhancing substances.

Hall says the Adderall, a prescription medication, belonged to an unidentified friend. Adderall is used to treat attention deficit hyperactivity disorder.

Hall didn't say what he had taken when his suspension was announced on Sept. 3, saying only that he used a stimulant in February to help him stay awake on the long drive. The fullback says the way the story has been presented people assume he took steroids and he wants to set the record straight.

He rejoined the Titans (3-1) on Monday and practiced with the team for the first time Wednesday.
