Cars of Martin Truex Jr., Kasey Kahne and Erik Jones penalized

Three of the fastest Monster Energy NASCAR Cup Series cars in practice and qualifying on Friday at Las Vegas Motor Speedway will be penalized today for violations caught during pre-qualifying inspection.

Erik Jones, who qualified eighth-fastest, was hit the hardest after he failed the weights and measures station three times. As a result, he will lose 15 minutes of Saturday practice time and his pit selection for Sunday's Kobalt 400 at the 1.5-mile track.

Martin Truex Jr., who was second-fastest in qualifying and will start on the front row alongside pole-winner Brad Keselowski for Sunday's race, failed the template station twice along with Kasey Kahne, who was seventh-fastest in qualifying. Both will lose 15 minutes of Saturday practice time as a result.
