Coach Herman said that Shack sprained a foot yesterday and the team is planning for him to be back for the opener. In the meantime, this should shift Kerstetter into center, move Angilau to RG and get Parker Braun firmly inserted into the starting lineup at LG for the remainder of camp. It was going to happen sooner or later, but this forces Coach Hand's hand (no pun intended) to take the training wheels off of Braun and get him going. Once Shack returns, the interesting part will be seeing who gets left out of the game of musical chairs ...
