Daytona Beach, FL -- (Sports Network) - NASCAR assessed a 50-point penalty to both driver Martin Truex, Jr. and car owner Teresa Earnhardt and fined crew chief Kevin Manion $50,000 after Truex's No.1 Chevrolet failed post-race inspection last Sunday at Texas Motor Speedway.

During inspection, NASCAR officials discovered the front of Truex's car was too low and therefore did not meet the required height specification.

In July, the team was penalized after the right rear quarter panel on the No.1 car was found to be too high during post-race inspection at Chicagoland Speedway. Truex and Earnhardt sustained a 25-point loss each, while Manion was fined $25,000 and placed on probation until December 31. Manion remains on probation for the remainder of the year following the Texas violation.

Truex dropped two positions to 26th in points. He finished 14th at Texas.
