Former NBA All-Star Anthony Mason died Saturday morning at the age of 48, it has been confirmed.

Mason, a 2001 All-Star with the Miami Heat, played for six NBA teams over 13 seasons including five years with the New York Knicks. He was diagnosed with congestive heart failure earlier this month.

Mason had four surgeries following his heart attack and his three sons — Anthony Jr, Antoine and Armon — were at his side.

Known as a tenacious defender and "the enforcer" for the Knicks, Mason even served as security for rapper LL Cool J.

Away from basketball, Mason appeared in television shows and movies, sometimes playing himself. He also appeared in several music videos, including the Beastie Boys' "Root Down".
