The 6-4, 270-pounder played this season at Copiah-Lincoln Community College in Wesson, Miss.
This season he earned All Region XII honors in his first season of play at Co-Lin after redshirting in 2007. As a high school player Fairley earned distinction as both a football and basketball standout at Williamson, playing in postseason All-Star games in both sports.
Rated a four-star prospect by Scout.com, Fairley is expected to play either strongside defensive end or defensive tackle on the next level and compares athletically to former Auburn and current Dallas Cowboys standout Jay Ratliff.
Fairley, who redshirted one season, will have three years of eligibility at the Division I level.
Recruited by a large number of colleges as a high school senior include FSU, Alabama, LSU and West Virginia, he stuck with his commitment throughout the past two years. Not even a change in coaching staffs at Auburn changed his mind.
On Wednesday, he drove home from junior college to Mobile to sign papers at Williamson High School and faxed them to Auburn.
Another Mississippi juco star, linebacker Eltoro Freeman from Benjamin Russell High in Alexander City, Ala., also could be signing with the Tigers in the juco early signing period. Prior to the coaching change he was solid to Auburn, but has been taking a late look at Ole Miss.
The Tigers were also expected to sign prep school running back Onterio McCalebb from Fort Meade, Fla., High this month. However, with the change in coaching staffs that is still to be determined. He is expected to get an in-home visit on Saturday with Clemson coaches.
McCalebb, who played at Hargrave Military Academy in Virginia this fall, took an official visit to Clemson last weekend adn said the AU Tigers and Clemson Tigers are running neck and neck now.
