Louisiana born MMA fighter dies at Arizona gym

A Louisiana-born welterweight mixed martial arts fighter has died while training at an Arizona gym for an upcoming match.

KPHO-TV reports that 33-year-old Sam Young died this week after he collapsed at Keep Punching gym in Scottsdale. Authorities say the father of two was later pronounced dead at a local hospital.

The Maricopa County Medical Examiner has not yet determined the cause of his death and could not say if his training or fighting were a contributing factor in his death.

Young, whose nickname was "the Sandman," was also a personal trainer at Maximum Fitness and the Keep Punching gyms, both in Scottsdale.

Michael King is a manager at the newly-opened, Keep Punching and one of Young's close friends, called the death shocking.
