chuck is right. They will elevate one of the WR and have 5 on the active roster for the game. Which is fine.
They have 3 guys on the PS, all of which could receive some consideration to be the #5 guy. They don't have a hole at WR.
They may have a hole at punt return, unless they feel Covey is the guy there. As stated above, returning has been minimized in the current game, but you do need a guy who can field them cleanly. Who's the #2 guy in case Covey gets hurt? Quez? Gainwell?
