The NFL has suspended Fred Davis for the next four games, so basically the season.

Fantasy Advice: OL Trent Williams will also miss the rest of the year with the same suspension, which is reportedly due to multiple failed drug tests. This is bad news for an already iffy Redskins offense. Logan Paulsen now gets the nod, but is not a good fantasy option. He's predominantly a blocker and not much of a receiving threat. This does nothing to help Davis' future while playing in a contract year.
