A boxer recently quit a boxing match after he was knocked down. He simply spit his mouthguard out after he got up from the canvas and walked out of the ring.

This comes after an NFL player "retired" from the sport at halftime a few weeks ago. Yes, athletes are just walking away from their respective sport while still in action.

The boxer who quit the match is Kaywann Sistrunk. He walked out of the ring in the third round.
