ESPN reports that testing performed by a second, independent laboratory supported the idea that Jeremy Mayfield
supported the results that left Sprint Cup driver Jeremy Mayfield indefinitely suspended for failing NASCAR’s substance abuse policy, court documents said. Results of the test and the name of the individual tested were blacked out, but a NASCAR spokesman confirmed they were identical.
The documents, part of NASCAR’s response to Mayfield’s lawsuit to have his indefinite suspension lifted, show that Medtox Laboratories in Minnesota tested both his "A" and backup "B" samples last week and "confirmed the presence" of a substance that is blacked out in the filing.
NASCAR claims Mayfield tested positive for a "dangerous, illegal, banned substance" and should not be allowed back on the track. It was revealed in open court two weeks ago that the drug was amphetamines.
