I watched most of the Pocono race on Sunday. Hamlin finished first, Kyle Busch second, Chase Elliot third. Apparently post race inspection turned up something on the front of two JGR cars that disqualified them and Chase Elliot was given the win. Haven't seen that happen before.
JGR isn't appealing so there must have been something more than a ticky tack violation at play.
