NASCAR has suspended two crew members for failing random drug tests.

One of the two suspensions issued Tuesday was to Lee Dodson, a mechanic on Clint Bowyer's car. Michael Waltrip Racing fired Dodson upon learning he'd failed a drug test.

The other suspension was issued to Frank Earnhardt, who NASCAR identified only as a crew member for a Nationwide Series team.

JR Motorsports said Earnhardt did not work for its organization, and a spokesman said the crew member was not believed to be a member of the extended Earnhardt family.

Anyone suspended for failing a NASCAR drug test must complete the "Road to Recovery" program before they are eligible for reinstatement.
