Vandervelde had been out since late July with a back injury, which required surgery a little more than two weeks ago.
The move is less surprising with back-up center David Molk playing exceptionally in second-team action this summer. The only surprise is that Vandervelde wasn't simply placed on IR.
Vandervelde played sparingly over the previous three seasons. He was a part of a 2011 class that proved disastrous. The only three remaining players from that draft on the roster are Jason Kelce, Casey Matthews, and Alex Henery.
