DAYTONA BEACH, Florida (AP) — Jeremy Mayfield missed Thursday’s deadline to enter this weekend’s Coke Zero 400 after successfully fighting NASCAR to get back behind the wheel following a failed random drug test.

His only hope for participating in Saturday’s race at Daytona International Speedway is as a relief driver, a change NASCAR must approve.

With that looking like a long shot and Mayfield yet to arrive at Daytona, NASCAR questioned the need for the injunction.

“Jeremy and his legal team asked for a temporary injunction for emergency relief because it was necessary apparently to come compete here in Daytona,” NASCAR spokesman Ramsey Poston said. “Apparently, he’s not here and it appears as if he’s not going to compete this weekend, which would raise some questions on how much of an emergency it really was.”

As the cars fired their engines on Thursday for practice, the Mayfield watch ended roughly 24 hours after a federal judge lifted the indefinite suspension and cleared him to race at Daytona.

Mayfield’s absence calmed at least one driver, who was admittedly uncomfortable driving against Mayfield now that NASCAR said he tested positive for methamphetamines in a urine sample collected on May 1.

“A federal judge releasing someone to drive without clarifying everything, that’s not cool,” said Ryan Newman, one of the most vocal drivers about drug testing since Mayfield’s suspension. “People make mistakes. I hope the judge didn’t make one.”

Mayfield sued NASCAR over the suspension, which covered his roles as owner and driver of the No. 41 Mayfield Motorsports Toyota. On Wednesday, U.S. District Court Judge Graham Mullen issued a temporary injunction based on the argument that NASCAR’s testing system is flawed.

Although Mayfield said after the ruling he intended to travel to Daytona, he wasn’t sure he’d be able to compete because of the short turnaround.

He’s admittedly cash-strapped, revealing in an affidavit last week that since his suspension on May 9 he’s had to lay off 10 employees, borrow money from family and sell personal assets to cover his living expenses. Triad Racing Technologies also is suing Mayfield for more than $86,000 for parts, pieces and chassis work he allegedly owes the company.

The outstanding balance would make it difficult for him to purchase a motor to use in the No. 41, and he also would have had to pay a $5,005 late entry fee to bring his own car to Daytona.

His other option was finding a team owner willing to give him a ride. Ten teams are trying to qualify for eight open spots in Saturday’s race, but only a handful likely would consider making a driver change to accommodate Mayfield.

Of them, four said they weren’t interested.

“Whether he’s right, wrong or different right now, he’s marked,” said Tommy Baldwin, an interim crew chief for Mayfield in 2007. “And that’s going to hurt him probably for the rest of his career.”
