"Ultimately making sure our team is healthy down the stretch is of the utmost importance. We wouldn't be in this situation here if we didn't feel like it was necessary to get guys 100 percent healthy, and that's what we are going to do. As I said, there are no long-term fears in this situation, but we want to make sure our guys are healthy."
