The 6-foot-5, 298-pound defensive lineman racked up five tackles, one-and-a-half sacks, intercepted a pass and recovered a fumble.
He became the first player to get an interception and fumble recovery in the same game since Sen’Derrick Marks against New Mexico State in 2007.
His efforts helped hold Mississippi State to 246 yards of total offense.
Fairley is now tied for the team lead in both tackles for loss (four) and quarterback sacks (three).
He is currently tied for second in the SEC in sacks and tied for third in tackles for loss.
The honor marks the second time in as many weeks an Auburn player has been recognized as SEC Player of the Week, after quarterback Cameron Newton was named the SEC Offensive Player of the Week following Auburn’s season-opening victory over Arkansas State.
The Mobile, Ala., native appeared in 13 games last season and started in two.
Fairley recorded 28 tackles, with three-and-a-half tackles for loss, and made his first career sack against Georgia Nov. 14, 2009.
