Not sure Selvin is big concern yet. No idea if he is truly healthy, the last time he was on the field he lasted one play. I don't believe the Bronco's are sure either, I would have expected at least one RB cut if they were. Unless I missed some news they still have, Hillis, Young, Pope, Bell, Larsen(FB), and Pinnock(FB) on the active roster. If Selvin makes it thru the game healthy i would expect them to drop at least one. The fact that they are still keeping 2 FB on the roster seems to imply they will be going with Hillis at RB fulltime at least this week. If he is dominate again and they keep winning, it seems unlikely they would change.
I know that trying to figure out what Shanahan will do is futile, but does he really have any choices other than Hillis ?
