According to Dan Samuelson on the facebooks, he is going to transfer.

With great sadness, I have decided that my time at the University of Michigan is done. The past couple years have been wonderful, and something that I will never forget. I am beyond blessed for them. As time has come and gone, I've thought about what is best for myself in regards to football and obtaining the goal of playing time. In reality, that wasn't going to happen at Michigan.

Samuelson was a recruit on the 3/4 star borderline who decommitted from Nebraska in favor of Michigan late in the 2013 recruiting cycle. He redshirted as a freshman and didn't play last year, so he would have been a redshirt sophomore this fall. His departure brings the number of certainly available scholarships to 17 (4 open slots plus 13 seniors). There are a lot of redshirt juniors who may not get a fifth year on the roster, so Michigan is already close to being able to accommodate the full class of 25 they seem to be aiming for.
