Playoff driver Hamlin entered Martinsville 18 points below the elimination line but his path to the Championship 4 got tougher as the No. 11 JGR Toyota crashed in Turn 3 during practice.

WATCH: Hamlin reacts to practice crash

Hamlin told his crew on the radio that the throttle stuck which caused him to spin and back his car into the wall. He will start Sunday’s Xfinity 500 from the back of the field after skipping qualifying for his team to repair the rear damage.
