Mayfield Failed Independent Test

ESPN.com is reporting today that tests performed by an independent laboratory support the original findings that led to Jeremy Mayfield’s indefinite suspension from NASCAR.

The name of the individual and the specific test results were blacked out in court documents, but a spokesman for NASCAR confirmed to ESPN that the findings were identical. Medtox Laboratories tested Mayfield’s "A" and "B" samples last week, and discovered the same banned substance originally found by Aegis Laboratories, which oversees NASCAR’s drug testing program.

Attorneys for both Mayfield and NASCAR testified in court two weeks ago that the substance in question is amphetamines.

Mayfield's attorneys contend that a second, independent lab should have been used to test Mayfield’s "B" sample in the first place, and that the sample was compromised when opened for testing by Aegis Labs. A hearing is set for tomorrow in U.S. District Court, as Mayfield seeks a temporary restraining order that would allow him to compete in Saturday night's Coke Zero 400 at Daytona International Speedway.

Truex To Finish `09 With MWR: Despite published reports claiming that Martin Truex Jr. could move to Michael Waltrip Racing’s #55 Toyota as soon as next month’s race at Chicagoland Speedway, Sirius Speedway has learned that Truex will remain with Earnhardt-Ganassi Racing for the remainder of the season.

Sources close to the situation say that while an agreement to move Truex to the Waltrip camp for the final few races of the season could still come to fruition, contractual and sponsorship issues will almost certainly keep Truex in the #1 Bass Pro Shops Chevrolet for the rest of the year.

Waltrip, meanwhile, is expected to finish the 2009 campaign in his familiar NAPA Toyota. Sources say that Truex will steer a new, NAPA-backed #56 Camry in 2010, with Waltrip running a limited schedule of 10-12 races (including the season-opener at Daytona) in a companion #55.

Michael Waltrip Racing is expected to announce the moves in a press conference scheduled for July 7.

NASCAR Claiming Milwaukee Vendor Revenue: The Milwaukee Journal Sentinel reported today that Wisconsin Motorsports, promoter of the Milwaukee Mile, owes NASCAR nearly $1.9 million dollars for the NASCAR Nationwide and Camping World Truck races held there this month.

Claude Napier, head of Wisconsin Motorsports, signed an agreement the day before the races were scheduled to take place, stating that he was unable to pay NASCAR’s sanction fee for the events, and agreeing that all revenue from the races would go directly to NASCAR. An attorney for NASCAR subsequently sent a letter to the track’s vendors, concessionaires and program sellers, instructing them to forward the money they owe Wisconsin Motorsports to NASCAR, instead.

NASCAR has reportedly paid all of its teams for the two events.
