Christian chose the Tigers and announced his decision after taking an official visit to Auburn this weekend.
"Overall the visit was great," Christian said. "I loved the environment. I loved the game. I had a lot of one-on-one time with the players. I like the players. I can see myself being an Auburn Tiger."
Christian, who is rated as the No. 17 prospect nationally by Scout.com, attended Auburn's home football game vs. the Kentucky Wildcats this weekend on an official visit.
The visit was taken mostly for security for Christian, who said he had pretty much made up his mind after visiting Auburn for the Ball State game three weeks ago that he wanted to play for Coach Gene Chizik's Tigers. After seeing the campus again on a gameday he decided to tell the coaches he was going to be a Tiger.
"I told them last night," Christian said. "They were pretty excited. I knew last time (it was Auburn). I pretty much knew."
Christian, an honor student at Lowndes, plays both ways in high school, but he projects as an offensive lineman in college.
