NASCAR officials discovered what the sanctioning body said were illegally modified c-posts on Hendrick’s No. 48 Chevrolet during pre-qualifying inspection at Daytona International Speedway. Crew chief Chad Knaus was fined $100,000, and he and car chief Ron Malek were suspended for six races. Driver Jimmie Johnson and team owner Rick Hendrick were also docked 25 championship points. The team appealed those sanctions to the National Stock Car Racing Commission, but a three-member panel unanimously upheld the penalties earlier this month.NASCAR and team officials will present their respective cases simultaneously today, with Middlebrook empowered to uphold, overturn, increase or decrease the original penalties.
