Crew chief Chad Knaus of the #48 Lowe's/Kobalt Tools Chevrolet driven by Jimmie Johnson, speaks to the media prior to practice for the NASCAR Sprint Cup Series Subway Fresh Fit 500 at Phoenix International Raceway on March 2 in Avondale, Ariz. 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 appeal.
