Here is what has been reported so far, from Arkley twitter/blogs:
Brandon Purdum - had off-season surgery, is out a few more weeks
Kyle Kuhar - had off-season shoulder surgery
Jerid McCray - sprained knee - out a few weeks
Mike Lucas - limited practice for now, had an ankle sprain

Let's hope none of these are too serious, and they all are back soon.
