NASCAR ejected Johnson car chief Jesse Saunders because the car failed inspection three times. The Chevrolet passed on its fourth inspection. Saunders is responsible for setting up the Camaro.
Johnson is a seven-time NASCAR champion and the winningest active driver on the Vegas track, but he is off to a slow start this season. He crashed in all three races at Daytona International Speedway and was 27th last week at Atlanta. He's 35th in the Cup standings.
Ryan Blaney started from the pole in Vegas.
