AVONDALE, AZ - MARCH 02: Crew chief Chad Knaus of the #48 Lowe's/ Kobalt Tools Chevrolet driven by Jimmie Johnson, looks on from the garage area prior to practice for the NASCAR Sprint Cup Series Subway Fresh Fit 500 at Phoenix International Raceway on March 2, 2012 in Avondale, Arizona. NASCAR suspended Knaus for six races and fined him $100,000 for failing an inspection last week in Daytona. Knaus will continue his crew chief duties while Hendrick Motorsports appeals NASCAR's decision. An appeal date hasn't been announced. (Photo by Christian Petersen/Getty Images) less
