Tennessee spokesman Jimmy Stanton says Smith and the student argued about a woman late Saturday night, and other Volunteers players stepped in to "diffuse the situation." The Vols had already returned from South Carolina, where they lost to the Gamecocks 38-24 earlier in the day.
Stanton says there were no major injuries, but the student decided to press charges after he and Smith left the scene. Smith turned himself into police on a charge of assault with bodily injury on Sunday and was released on $2,000 bond.
Coach Derek Dooley said Sunday that he felt Smith used bad judgment and plans to handle Smith's punishment internally.
The Chattanooga, Tenn., native has 18 tackles in eight games this season.
