SAN FRANCISCO — A man who died in Oakland Police custody Saturday morning was a former NFL player, according to the Oakland Police Department.

Doug Martin, the former All-Pro running back for the Oakland Raiders and Tampa Bay Buccaneers, died at age 36, his family said in a statement Sunday.

Martin was arrested following a break-in at a home on Ettrick Street near the Oakland Zoo. Martin was taken into custody a little before 5 a.m.

Police say he had a medical emergency, and there was a brief struggle before he became unresponsive.

“Paramedic personnel arrived, provided medical aid, and transported the individual to an area hospital for further treatment. Unfortunately, the individual later died at the hospital,” Oakland Police Department said in a statement.

OPD said officers involved in the incident have been placed on paid administrative leave, to comply with departmental policy.

Martin was born in Oakland and grew up in Stockton.

“It is with great sadness to inform you all that Doug Martin passed away Saturday morning,” the family statement said, according to the .

Tampa Bay, where Martin spent six of his seven NFL seasons, called him a “fan favorite” who made “a lasting impact on our franchise.”

Just 5-foot-9, the Oakland, California-born star was known for his bruising style, earning him the nickname the “Muscle Hamster,” while amassing 5,356 and 30 touchdowns in seven NFL seasons, all but one with the Bucs.

A former Boise State player, he was a first-round pick (No. 31) of Tampa Bay in 2012, and immediately burst onto the scene, rushing for 1,454 yards and 11 TDs and catching 49 passes for 472 yards and another score in his first season, which resulted in a Pro Bowl nod. At the time, he had the third-most yards from scrimmage as a rookie in NFL history, trailing only Eric Dickerson (2,212 in 1984) and Edgerrin James (2,139 in 1999).

Martin’s best season came in his All-Pro year in 2015, when he rushed for 1,402 yards and six TDs and had 33 catches for 271 yards and another score.

He spent two more seasons in Tampa Bay after that, then finished his career in 2018 with the Oakland Raiders for one season.

Martin attended Boise State from 2007 to ’11, and ranks in the top 10 for career rushing yards and rushing touchdowns at the school. He was twice a first team all-conference honoree.

His death is being investigated by the Oakland Police Department’s homicide and internal affairs units, the Oakland City Police Commission, the Community Police Review Agency and the Alameda County District Attorney’s Office.
