CHARLOTTE, N.C. (AP) — NASCAR has given the attorney for Jeremy Mayfield a copy of the suspended driver's toxicology report.
Charlotte attorney Bill Diehl is representing Mayfield and requested the documents from NASCAR.
Mayfield was suspended indefinitely May 9 for failing a random drug test. NASCAR has not revealed what banned substance Mayfield used.
Mayfield has said he was never told what he tested positive for. The doctor who administers NASCAR's drug-testing program refuted that, saying he personally identified the substance in several conversations with the driver.
