Defending Sprint Cup champion Tony Stewart was docked six points by NASCAR on Tuesday for rules violations that occurred last weekend at Daytona.  Stewart's number-14 Chevrolet was issued a penalty for an unapproved open vent hose that was found during post-qualifying inspection. Stewart's crew chief, Steve Addington, was fined 25-thousand-dollars and placed on probation until August 22nd.  Stewart won last Saturday night's 400-mile Sprint Cup race at Daytona after starting 42nd. Next on the Sprint Cup schedule is the Lenox 301 at New Hampshire Motor Speedway. Our live coverage of the race on AM 1590 and FM 95.5 begins Sunday at Noon. Meanwhile, the United States Army has announced it will not return to NASCAR next season as a sponsor.  The Army currently sponsors Ryan Newman's number-39 car in the Sprint Cup Series.  Minnesota Congresswoman Betty McCollum has been trying to end military sports sponsorship programs and praised the announcement.  McCollum added that she would be meeting with officials from the National Guard to discuss their current sponsorship of Dale Earnhardt Jr.'s number-88 car.
