Auburn has dismissed defensive lineman Derrick Lykes from the football program, the Mobile Press-Register reports. Lykes is out for an undisclosed violation of team rules.
He was not listed on the105-man roster, released on Wednesday. Lykes redshirted at Auburn in 2008, before playing sparingly in 2009 and 2010.
He had 12 tackles last season, primarily on special teams. Lykes played in just three games last season, Chattanooga, Kentucky and South Carolina in the SEC Championship Game.
