Joe Gibbs Racing appeared to have enjoyed a banner day at Pocono, but all that changed not long after the M&M’s Fan Appreciation 400 came to a close.
JGR drivers Denny Hamlin and Kyle Busch finished 1-2 in the race, but their cars failed postrace inspections. The Nos. 11 and 18 cars were disqualified, making third-place finisher Chase Elliott the winner of the race.
“We were shocked to learn of the infraction that caused our two cars to fail NASCAR’s post-race technical inspection. We plan to review every part of the process that led to this situation,” Joe Gibbs Racing said in a statement.
NASCAR said they discovered material on the front fascia of both cars that could impact the aerodynamics of the vehicles.
