Newman finished fourth in Sunday’s Samsung 500, but violations were discovered during post-race inspection.

As a result, Newman and car owner Roger Penske have been penalized 25 championship driver and 25 championship owner points, respectively. Also, crew chief Roy McCauley has been fined $25,000 and placed on NASCAR probation until December 31.

It was determined during the inspection that the right-rear of Newman’s Dodge was 1/8 of an inch above allowed tolerances. NASCAR deemed that Newman was guilty of actions detrimental to stock car racing; having a car, car parts, components and/or equipment used that do not conform to NASCAR rules; and having a right rear quarter panel height that did not meet the required specification. 

With the 25-point penalty, Newman, the 2008 Daytona 500 winner, falls from a tie for eighth place with Greg Biffle to 10th place with a total of 876 points.

“We had an issue in post-race inspection on Sunday at Texas Motor Speedway,” said Penske vice president of operation Michael Nelson in a statement. “It is always our intention to follow NASCAR’s rules, and we regret this mistake.

“We look forward to getting back to the track this week and are focused on having a strong run in the No. 12 Alltel Dodge at Phoenix International Raceway.”
