Chase Briscoe and the No. 19 Joe Gibbs Racing team have been handed an L2-level penalty following Sundays Daytona 500 at Daytona (Fla.) Intl Speedway.

After Briscoes No. 19 Toyota was inspected further at the NASCAR R&D Center in Concord, N.C., officials discovered modifications to the spoiler of the race car.

The spoiler is a single-source vendor supply part that cannot be modified. The team was found in violation of Section 14.1 in the NASCAR Rulebook, which pertains to overall assembled vehicles rules and 14.5.8, which deals with the spoiler.

Among the penalties was Briscoe being docked 100 driver points and 10 playoff points. JGR was fined $100,000 and docked 100 owner points. They were also deducted 10 playoff points.

Briscoes crew chief, James Small, was suspended for four races, beginning this weekend at Atlanta Motor Speedway.

Todd Gilliland (No. 34 Front Row Motorsports Ford) and Cody Ware (No. 51 Rick Ware Racing Ford) were each docked 10 points, with both teams deducted 10 owner points due to a safety violation with ballast found outside the ballast container(s).
