Washington OL Joshua Garnett was originally planning on visiting Michigan for the Ohio State game. That changed, though, and he's now going to be in for the Notre Dame game on September 10th.
He has a top 11 right now, which Michigan is in. He plans on cutting that list down soon, and since he's already planning on visiting you can bet Michigan will be in the short list as well.
Just something to keep in mind, he and commit Erik Magnuson have become pretty good friends lately. Magnuson will also be in Ann Arbor for the Notre Dame game.
