He should not come back this year if it at all borderline. Even if there isn't an increased risk of paralysis, putting stress on the area before it is FULLY healed cannot be good for long term pain issues. The fact he is up and running does not mean he can do impact sports... yet. Hopefully he has a full recovery and in the meantime can keep the rest of his body in shape. Would love to have him back next year.
With Tre White, I wonder if they are concerned that he will experience swelling if he overexerts, or if he is still recovering his cardio. At least he didn't get obvously burned in those 15 snaps so it is a good start.
