Three star linebacker Sean Duggan (Cincinnati, OH) has named a top four schools of Boston College, Michigan, Duke and Virginia. It's pretty much what he had as a top five, except he's cut Wisconsin.
There's a slight chance that Duggan could make it up to Ann Arbor for the big game this weekend against Michigan State, but if not he'll take his official visit during the first or second week of December.
Right now he favors Boston College, and to be honest I don't see that changing. His official visit to the Eagles will likely be for their game against Clemson. Michigan, Duke and Virginia won't get to host him for a game, which is a major disadvantage. BC are also recruiting Duggan's teammate Steven Daniels, who would like to play college ball with Sean.
