Per an email I just received from UA:

Mal Moore will step down as athletics director, effective March 20, 2013, to become special assistant to President Judy Bonner.

"As many of you may know, due to factors related to my health, I am at a point that I can no longer fulfill my duties as athletics director in the true championship manner the position requires," said Moore. "While I have to focus on my health issue, I look forward to maintaining an ongoing working relationship with this great University as special assistant to Dr. Bonner. I know I can count on each of you to continue your unequaled support for me and The University of Alabama.

"I cannot adequately express what the University means to me. It has been a part of my life for more than 50 years, and I feel honored to have served the Crimson Tide as a player, coach and administrator. I am so appreciative of the University administration, coaches, staff, student-athletes and fans who have made my tenure as director so very meaningful, memorable and special."

The email also notes that Moore's successor will be named as quickly as possible.
