LONDON (AP) - NASCAR has suspended driver A.J. Allmendinger indefinitely after a test of his backup urine sample came back positive Tuesday.
Allmendinger originally was suspended July 7 after failing a random drug test taken in late June. His backup ``B'' urine sample was tested Tuesday by Aegis Analytical Laboratories in Nashville, Tenn.
NASCAR officials announced the results and subsequent suspension Tuesday night.
Officials did not announce what substance for which Allmendinger tested positive. Allmendinger has said he tested positive for a stimulant he has not revealed, but denied knowingly taking a banned substance.
Earlier Tuesday, NASCAR CEO Brian France said he is confident in the series' drug testing program.
