Jimmie Johnson ran into trouble twice and has now finished out of the top 10 in four consecutive races for the second time since 2009.
Johnson recovered from a flat tire on Lap 8. But his team couldn’t fix the damage after he smacked the wall while running fifth with 49 laps remaining.
“I am clueless (as to what happened),” said Johnson, who finished 39th and dropped to sixth in points. “The car went straight down into the Tunnel Turn. Normally when (a tire) goes down, they explode. There was no explosion. It just went straight (into the fence).”
Kyle Busch’s engine failed on Lap 24, resulting in a 42nd-place showing that dropped him four places to 10th in points.
