Four Nextel Cup crew chiefs were suspended and their teams were fined a total of $150,000, 150 driver points and 150 car owner points Tuesday afternoon at Daytona International Speedway. Evernham Motorsports took the biggest hit as its lead car, the No. 9 Dodge of driver Kasey Kahne, lost its team director, Kenny Francis, for four races beginning with Sunday's Daytona 500; Kahne was docked 50 driver points and owner Ray Evernham 50 owner points. Kahne's teammates, Elliott Sadler (No. 19) and Scott Riggs (No. 10) lost their team directors, Josh Browne and Rodney Childers, respectively, for two races apiece; Sadler and Riggs will lose 25 driver points each, and owners Evernham (19) and James Rocco (10) will be docked 25 owner points following the Daytona 500. Roush Racing's No. 17 Ford team for driver Matt Kenseth was hit with an equivalent penalty as Kahne's -- with both infractions involving "air improperly ducted into the car," according to NASCAR vice president of competition Robin Pemberton. Kenseth's crew chief Robbie Reiser will serve a four-race suspension and he was assessed a $50,000 fine. Kenseth will lose 50 driver points and owner Jack Roush 50 owner points.
