Mal Moore, who stepped down as Alabama's athletic director less than two weeks ago, died Saturday, according to USA Today. He was 73.
The Crimson Tide's AD was battling pulmonary difficulties.
He was hospitalized at Duke University Medical Center in Durham, N.C., since March 13 and officially resigned on March 20. Bill Battle took over for Moore a week ago.
Moore was part of Alabama athletics for more than 50 years as a player, coach or administrator. He was part of 10 national football titles.
He played on legendary coach Paul "Bear" Bryant's 1961 national championship team as a backup quarterback. Moore was later an assistant coach under Bryant and Gene Stallings. He then spent five years as an associate athletic director and became AD in 1999.
Moore hired Nick Saban as football coach before the 2007 season. Saban led the Crimson Tide to three national titles in the last four years.
