NASCAR has asked an appeals court to overturn the injunction that lifted Jeremy Mayfield's indefinite suspension for a failing a random drug test.

NASCAR made its request Wednesday to the 4th U.S. Circuit Court of Appeals. In the filing, NASCAR argues allowing Mayfield on the track presents potentially fatal consequences to other drivers, teams and fans.

The filing claims U.S. District Court Judge Graham Mullen relied on incorrect information when he lifted the suspension last week.

NASCAR has said Mayfield tested positive for methamphetamine, but the driver has denied using the illegal drug. His lawyers contend NASCAR's drug policy is flawed because it does not meet federal guidelines.
