NASCAR has suspended three Sprint Cup Series crew chiefs for infractions at Charlotte Motor Speedway.
Greg Biffle crew chief Brian Pattie was fined $50,000 and suspended for all the activities through June 15. Biffle also was docked 15 driver points because the Roush Fenway Racing Ford had a body design that was either not submitted to NASCAR for approval or did not comply with the approved body designs.
AJ Allmendinger crew chief Randall Burnett and Kurt Busch crew chief Tony Gibson were both fined $20,000 and suspended for this weekend's race at Pocono for not having properly affixed lug nuts in Sunday's event at Charlotte.
Tony Stewart crew chief Mike Bugarewicz was placed on probation through Dec. 31 for infractions to body design found in pre-race inspection.
