Jeremy Maclin (undisclosed) has returned to his hometown of St. Louis for further testing. It's time to get concerned. Maclin hasn't practiced yet, appears noticeably thin and is now leaving the team. He's going back to St. Louis to try to identify the mysterious illness that has apparently bothered him since last spring. At this point, Maclin is no lock to be ready for Week 1. Owners drafting early need to tread lightly until more details are revealed.
