An expert witness for suspended driver Jeremy Mayfield does not have the medical degrees or certifications he listed in his qualifications, NASCAR said yesterday.

In a motion filed in U.S. District Court in Charlotte, N.C., NASCAR asked that Dr. Harvey MacFenerstein's sworn affidavit be dismissed from Mayfield's lawsuit because the expert falsely represented himself on six counts. MacFenerstein is president of Analytical Toxicology Corp., a drug-testing laboratory in San Antonio, Texas.

Attorneys for Mayfield filed a sworn affidavit from MacFenerstein that said NASCAR's drug-testing program is flawed and does not meet federal workplace guidelines. His findings were the basis of Mayfield's May 29 argument that his indefinite suspension for a failed drug test should be lifted.
