Doug Martin, a former All-Pro running back for the Tampa Bay Buccaneers, has died at the age of 36.

TMZ reported the initial news of Martin's death.

A stalwart, all-around running back, Martin made two Pro Bowls (2012, 2015) and was selected to one First-Team All-Pro season (2015) during his NFL career. Martin had two separate seasons with at least 1,400 rushing yards and even nearly broached 2,000 yards from scrimmage in 2012. He finished his professional playing days with over 5,300 rushing yards and over 1,200 yards receiving. Martin was often affectionately referred to as "Muscle Hamster" because of his powerful stature and a bruising play style despite only standing at 5-foot-9.

Rest in peace to an understated NFL legend:

Per TMZ, it is not clear exactly when Martin died or why at the time of this writing. We will update this story accordingly once we learn more.

UPDATE: Per Pro Football Talk, Martin reportedly died while in the custody of police in Oakland:

Early Saturday, Oakland police were responding to reports of a home invasion in East Oakland. The Oakland Police Department issued a statement that, simultaneous to receiving reports of a burglary, they were informed that the suspect was having a “medical emergency.” A “brief struggle” with the suspect followed. The person became unresponsive after being taken into custody. He received medical assistance from paramedics at the scene, before being taken to the hospital.
