Daytona Beach, FL -- (Sports Network) - Sprint Cup Series driver and team owner Jeremy Mayfield was not present at Daytona International Speedway on Thursday, one day after a federal judge granted him a temporary injunction to race again, beginning with this weekend's Coke Zero 400.

Mayfield had until 3 p.m. (et) to officially enter his team for Saturday's 400-mile race at Daytona.

On Wednesday, Mayfield was granted an injunction by U.S. District Court Judge Graham Mullen in Charlotte, allowing the 40-year-old driver to continue competition while his case against NASCAR proceeds. Mullen noted the likelihood of a false positive in issuing the temporary injunction.

After testing positive for methamphetamines on May 1, Mayfield became the first driver to be suspended indefinitely since NASCAR's revised drug policy went into effect earlier this year. Mayfield repeatedly denied he used illegal drugs, claiming his positive test resulted from taking the prescription drug Adderall XR, used to treat attention deficit hyperactivity disorder, and a double dosage of the allergy medication Claritin-D.

Mayfield has also claimed his suspension has led to struggles in financial and sponsorship support, and has forced him to lay off 10 crew members from his team.

This year, Mayfield formed his own team and qualified for five races, including the Daytona 500.
