NASCAR issued L-1 penalties to all three of the Joe Gibbs Racing teams in the Monster Energy NASCAR Cup Series Tuesday for infractions discovered during pre-race inspection at Michigan this past Sunday.  The infractions were due to splitters that did not meet rules specifications.

The No. 18 team of Kyle Busch, No. 11 team of Denny Hamlin and the No. 20 team of Erik Jones were all sent to the rear of the field prior to the Michigan race when the violations were found.

Busch finished fourth Sunday, Hamlin 12th and Jones 15th.

The respective crew chiefs for each team Mike Wheeler (No. 11 team), Adam Stevens (No. 18 team) and Chris Gayle (No. 20 team) all were fined $25,000.  The car chiefs — Brandon Griffeth (No. 11 car chief), Nate Bellows (No. 18 car chief) and Jason Overstreet (No. 20 car chief) — all were suspended from the next Monster Energy Series points event.

The Cup Series is off this weekend, so the penalties will be served at Sonoma Raceway next weekend

There was no immediate word on whether Joe Gibbs Racing officials planned to appeal.
