DAYTONA BEACH, Fla. – Denny Hamlin was penalized 75 NASCAR Sprint Cup Series driver championship points and his crew chief, Darian Grubb, was suspended for six races on Tuesday following NASCAR’s thorough inspection of Hamlin’s car.
Hamlin’s No. 11 FedEx Toyota finished third in Sunday’s Brickyard 400, but post-race inspection of the car yielded the rear firewall block-off plates weren’t sealed off. NASCAR ruled it a P5 level penalty, which involves four violations of the sport’s rulebook.
It results in a slew of penalties: 75 lost points for Hamlin, a 75-point deduction in owner points for Joe Gibbs Racing, the six-race suspension for Grubb and car chief Wesley Sherrill, a $125,000 fine for Grubb and six months’ probation for Grubb and Sherrill.
Hamlin fell from 11th to 21st in Sprint Cup standings following the point penalty.
