Duke has dismissed freshman linebacker Trent Mackey from its football team for violating team standards, coach David Cutcliffe announced Thursday.
Another freshman, defensive back Randez James, has been suspended from the team and will miss spring practice.
Mackey appeared in 11 games in 2008 and made 10 tackles. He is no longer enrolled at Duke.
James did not play in a game last season. His status as a team member will be evaluated at the end of the spring semester.
