I have him in a keeper and nobody has even come sniffing. I don't see anything that reduces his value from where it is now unless he doesn't play at all (unlikely). The closer to week 10 the more value he has.
If I am out of it when he comes back (or just before) then I can trade him for a cheaper keeper next year. If I am not, by some miracle, then he boosts my team.
For now, he is a dead roster spot on my team but I have not seen anything on the waiver that is worth more than his potential at the end of year.
