The injury rules for teams have changed over the year, and basically every player that misses a day of practice has to be listed as “questionable”. There is no more “probably” or “doubtful” (I think). So, this is really just a list of guys that missed a day of practice on this short week.
I would expect all, or most, of these players to appear in the game vs. the Cowboys. However, most of them are probably not as 100%. Russell Okung and Joe Barksdale are the ones I’d be the most concerned about, because the Dallas pass-rush with Demarcus Lawrence and David Irving has been dominant (at times) this season.
This game will likely be won or lost on the injury report of the Cowboys, because they’ll need full output from Lawrence, Tyron Smith, and probably Jeff Heath if they hope to protect their own QB and put pressure on Philip Rivers.
