"We have high standards for our players," Malzahn said. "They will represent the team and Auburn the right way."
A native of Mobile, Ala., Sigler was recruited out of B.C. Rain High as a defensive lineman although he played mostly linebacker in high school. Praised each of the last two seasons heading into the year, Sigler has battled nagging injuries and played very little in a back-up role.
In 18 games in his career, Sigler recorded 12 tackles. He played in five games in 2012, making just two tackles.
With his dismissal Auburn will enter spring practice with Jeffrey Whitaker, Kenneth Carter, Gabe Wright, Angelo Blackson, Jabrian Niles, Tyler Nero and junior college transfer Ben Bradley at the defensive tackle position.
