NASCAR docked the No. 1 Earnhardt Ganassi Racing team 50 points in the driver and owner standings after the team was found to be too low during postrace inspection at Texas Motor Speedway. As a result, Truex drops from 24th to 26th in the championship.
Manion was fined $50,000 and remains on NASCAR probation until Dec. 31, 2009.
Truex finished 14th in Sunday's Dickies 500 at TMS.
