I imagine most of the injured players will try to play if they possibly can. Both Hali and Houston won't be nearly as effective if they go, but they're probably still better then KC's alternatives. Would think Hali is most likely to sit, despite reports indicating otherwise, because would think it would effect his explosion off the line.
Houston can always take a painkiller and be like Von Miller of 2011
No idea on the Broncos front, but hoping Julius Thomas goes.
