NASCAR's Jeremy Mayfield fails drug test

DARLINGTON, S.C. — NASCAR Sprint Cup Series driver and owner Jeremy Mayfield has been suspended indefinitely after failing a random drug test administered at Richmond (Va.) International Raceway last week.

"We have zero tolerance for violation of our substance-abuse policy," said Jim Hunter, NASCAR's vice president of corporate communication. "We've made it very clear that we're going to stick to that. . . . Overall I think the random testing program is working. I think you will find that it is heartily endorsed by everyone in the garage. There's just no place for substance abuse in our sport." Mayfield's No. 41 Mayfield Motorsports team can operate only if it obtains a different owner and driver. The team plans to announce an interim driver and owner this week.

Mayfield, 39, said the positive drug test was a result of a reaction caused by mixing his prescription medication and over-the-counter medication.

Hunter declined to comment on what substance caused the suspension, but he said it was not alcohol-related. He also said the suspension is not appealable.

Tony Martin, a crew member for the No. 34 Sprint Cup car driven by John Andretti, and Ben Williams, a crew member for the No. 16 Roush Fenway Nationwide car, driven by Matt Kenseth, also failed tests administered at Richmond. Both have been suspended indefinitely.

NASCAR enacted a random drug-testing policy this season for crew members, crew chiefs and drivers. NASCAR can also test any competitor upon suspicion.
