In honor of Flashback Friday, we remember the wild last-lap fracas involving Denny Hamlin and Joey Logano at Auto Club Speedway in 2013.

A week after the former teammates-turned-rivals and members of their respective crews clashed at Bristol Motor Speedway, the bad blood continued to simmer at the 2-mile Southern California track.

After already making contact on the penultimate lap at Fontana, Logano and Hamlin raced side-by-side down the backstretch and into the final turn before bouncing hard off one another -- contact that sent Logano into the outside wall with the right side and Hamlin head-first into the inside wall as Kyle Busch scooted by to score the win.

On top of losing the race and destroying his car, Hamlin suffered a compression fracture of his lower back -- an injury that forced him to sit out the next four races and ultimately contributed to him missing the Chase for the Sprint Cup for the first and only time in his career.
