It goes without saying that this is a troubling way for the rookie wide receiver to begin his career. If he isn't cleared for non-padded practice with teammates, it's hard to imagine Swope receiving the green light for training camp next month. It's believed Swope suffered four concussions during a college career in which he played with Ryan Tannehill and became the Aggies' all-time leading receiver.
It's unclear if the Cardinals entered this situation with their eyes open, or if Swope's lingering symptoms come as an unwelcome surprise. If healthy, Swope is in position to slide behind Larry Fitzgerald, Michael Floyd and Andre Roberts on the Cardinals' depth chart.
That's all on hold for now, however.
