NASCAR has fined Tony Gibson, crew chief for Kurt Busch, $10,000 for an improper body modification at Pocono Raceway.
Gibson's current probation has also been extended until Dec. 31, which he has been serving due to a lug nut violation at Charlotte Motor Speedway in May.
The right-rear quater panel of Busch's No. 41 Stewart-Haas Racing Chevrolet was found to be modified during post-race inspection after Monday's Pennsylvania 400.
