CHARLOTTE, N.C. — The attorney for Jeremy Mayfield says an independent drug test on the NASCAR driver came back negative for methamphetamine.

In court papers filed Tuesday in U.S. District Court, Mayfield’s attorneys say Mayfield provided a urine sample to a lab in Hickory, N.C., at about 9 p.m. July 6 and that it did not reveal the presence of methamphetamine.
NASCAR says a sample it collected about 40 minutes earlier that night tested positive for the illegal drug.
NASCAR first suspended Mayfield on May 8 after he failing a random drug test eight days earlier. He has denied every using methamphetamine.
