Watch: Leaders wreck with four laps to go in Ambetter Health 400

With four laps to go in Sunday's Ambetter Health 400 at Atlanta Motor Speedway, two of the fastest cars of the day had their races ended. 

Austin Cindric and William Byron spun on the exit of turn two after race leader Kyle Larson pinched Cindric into the wall on the exit of turn two. Byron and Cindric spun down the backstretch, hitting the inside wall hard. Both cars sustained major damage in the crash and were eliminated from contention.
