NASCAR announced on Tuesday that Sprint Cup driver A.J. Allmendinger has been suspended indefinitely for violating the sport's substance abuse policy. NASCAR had Allmendinger's B sample tested on Tuesday, and presumably it came back positive as well.

According to the NASCAR rule book, NASCAR will now provide Allmendinger with a letter outlining the process for reinstatement.

Allmendinger had been temporarily suspended on July 7. NASCAR has not specified the substance that turned up in Allmendinger's tests. (Allmendinger’s business manager has said that the driver tested positive for a stimulant and that he did not knowingly take a banned substance.)
