The Buccaneers will be missing two of their defensive starters against the Bears on Sunday.
Davis played every snap last week and made six tackles, but he picked up a toe injury that will keep him from doing so again this weekend. Kancey has battled a calf injury since early in training camp and only played 11 snaps last week.
Safety Christian Izien is listed as questionable. Izien, who played 36 defensive snaps in the win over the Vikings, is in the concussion protocol.
