Out players stay Out until the NFL injury updates
There should be a presumption that an injured player out in Week X will still be out in Week X+1 unless and until the team issues a Game Status report (Friday before a Sunday game) clarifying whether the player is something other than Out.
James DeRosa commented
Currently, a player listed as "Out" may be place in the IR slot. Tuesday rolls around and all players' health status is erased. A manger then must cut a player and move the IR player to the active roster to make any waiver/FA claims until the league announces on Wednesday that the player is "Out" again. The players status should remain "Out" until the league officially changes it in Wednesday. Otherwise the IR slot is (mostly) useless.
