Mayfield subsequently filed a lawsuit against NASCAR that was dismissed by the state court on the grounds that he had set aside his rights to sue the sanctioning body when he signed to race for them. The case is currently before the US Court of Appeals, with the next hearing not expected to take place before January at the earliest.
Before his suspension, Mayfield had 433 career Cup and 36 Nationwide starts over the course of 16 years, with five Cup race wins and two Chase campaigns. His car owners included the Sadler Brothers, Cale Yarborough, Roger Penske, Ray Evernham and Gene Haas before setting up his own team Mayfield Motorsports shortly before his suspension.
In a separate story, NASCAR announced Thursday that Charles Day, a crew member for the #66 Cup HP Racing team driven by Michael McDowell, had been indefinitely suspended for violating the sanctioning body's substance abuse policy. Day was found to have violated Sections 12-1 (actions detrimental to stock car racing) and 19 (violation of the NASCAR substance abuse policy) of NASCAR's current rule book.
