Former defensive standout Tony Dunn returns again this fall for his fourth season on Barnes' staff as a volunteer assistant.

A four-year player for the Hornets, Dunn completed his eligibility in the fall of 2008 after playing in 29 games for coach Paul Barnes. A starter for his final two seasons, Dunn finished his career with 82 tackles including 47 solo and six sacks.

He ended his career No. 6 all-time in sacks and ninth in tackles for loss. In 2007, he earned All-USA South honors.

Dunn again assists along the defensive line.
