NASCAR: Several crew chiefs suspended, teams penalized

Greg Biffle's crew chief has been suspended for two races, while crew chiefs for Kurt Busch and AJ Allmendinger will miss Sunday's race at Pocono after NASCAR assessed several penalties for violations during the Coca-Cola 600.

Biffle's car was randomly chosen to go to NASCAR's research and development for examination after Sunday's race. Biffle's crew chief Brian Pattie has been fined $50,000 after several infractions were found during post-race inspection, including an unapproved body design. Biffle was issued a 15-point penalty that drops him down a spot in the standings to 24th, 79 points behind 16th. The team also loses 15 owner points.

Randall Burnett, Allmendinger's crew chief, and Tony Gibson (Busch's crew chief) violated the recently clarified lug nut rules that call for all five lug nuts to be "installed in a safe and secure manner at all times." Allmendinger was missing a lug nut; Busch's were not securely fastened. Allmendinger is a point behind Ryan Newman for 16th.

Mike Bugarewicz, Tony Stewart's crew chief, has been put on probation for the rest of the year for illegal body modifications which were found in prerace inspection. 

In addition, the No. 27 of Paul Menard got a second warning after failing pre-qualifying template inspection three times. The team was given a writing warning and will lose 15 minutes of practice time for the next race. The cars of Aric Almirola, Matt Kenseth, Dale Earnhardt Jr. and Jimmie Johnson failed inspection several times; Almirola and Kenseth failed laser inspection and Earnhardt and Johnson failed template inspection. All got written warnings.
