The program confirmed the news Friday afternoon citing "personal reasons" as the reason for Dixon's departure.
"We certainly hate to see any player leave our program, but we understand the situation and we wish him the best of luck in the future," head coach Nick Saban said in a statement.
Dixon, a 6-foot-1, 191-pound corner out of Miami, Fla., came to Alabama from East Arizona Community College in January.
Alabama's secondary took a hit with several players moving on to the NFL, leaving Saban a fairly inexperienced group to develop this year.
Thursday after practice, Saban said of the unit he works with everyday: "We've got a ways to go, that's all I can tell you. There are guys that have some good promise and some guys that have played really good football for us here. They're trying to provide some of the leadership we need to develop some other players. To me, that's a challenge for us right now to see how rapidly we can get some of those young players to develop with consistency.
"How quickly these guys develop is going to be really important to how successful we are on defense."
With Dixon's departure, eyes are on another JUCO transfer Deion Belue and juniors Dee Milliner and John Fulton to make an impact.
The Tide has its first scrimmage tomorrow to find, as Saban said, "who the football players are."
