CHARLOTTE, N.C. (AP) – NASCAR has given Jeremy Mayfield’s attorney a copy of the suspended driver’s toxicology report.

Charlotte attorney Bill Diehl requested the documents from NASCAR, spokesman Ramsey Poston said Wednesday.

NASCAR complied and sent the paperwork Tuesday to Diehl, who has represented several Charlotte-area athletic figures in high-profile cases. He defended former Charlotte Hornet David Wesley, convicted of reckless driving but acquitted of racing teammate Bobby Phills right before Phills’ fatal car accident, and current New Orleans Hornets owner George Shinn in civil suit against a woman who alleged a sexual assault.

Mayfield was suspended indefinitely May 9 for failing a random drug test. NASCAR has not revealed what banned substance Mayfield used. A person familiar with the test results has told The Associated Press that Mayfield’s case is not steroid-related, which means the results showed the use of an illegal recreational drug. The person requested anonymity because the results are supposed to remain confidential.

Mayfield has said he was never told what he tested positive for.

“I have no paperwork whatsoever for what I tested for,” Mayfield told reporters from the infield of Lowe’s Motor Speedway during last Saturday night’s All-Star race activities.

“They didn’t say what I took. They don’t know what I took.”

Dr. David Black, CEO of Aegis Sciences Corp., which runs the testing program, has refuted Mayfield’s statement, saying he specifically identified the drug in several conversations with the Sprint Cup driver over a three-day period after NASCAR suspended him.

“I spoke with him about his positive test result on the day he was suspended, and I spoke to him directly about the test result,” Black said. “Yes, by name of what he tested positive for.”

Black said Mayfield would have to obtain a copy of the test results from NASCAR, not Aegis. Until Diehl’s request, NASCAR spokesman Ramsey Poston said Mayfield had not asked for a copy.

Mayfield insists the use of a prescription drug with over-the-counter allergy medication Claritin-D led to his positive result, an explanation Black has repeatedly rejected.
