That official said those witnesses would testify to both recent and long-term use.
Those remarks followed a court filing Monday by NASCAR attorneys U.S. District Court. The filing asked U.S. District Court Judge Graham Mullen to lift an injunction he granted Mayfield earlier this month so he could return to racing. Mayfield was suspended May 9 after a positive test for what NASCAR later identified as meth.
An appeals court last week put on hold Mullen's injunction, but Monday's filing is part of a larger lawsuit between NASCAR and Mayfield.
The NASCAR official declined Monday to further characterize the witnesses to Mayfield's meth use, but in Monday's court filing, NASCAR attorneys said they were reluctant to testify after Mayfield angrily responded to similar testimony from his stepmother, Lisa Mayfield. Jeremy Mayfield said Lisa Mayfield is "basically a whore" and accused her of killing his father, who died in 2007.
Attorneys say Mayfield apparently contacted one of the unnamed witnesses to convince her that despite her recollection, he never used drugs. ThatsRacin
