Forall the latest fantasy updates, follow uson Twitter .WEEK 16 STANDARD RANKINGS: | | | | | Keenan Allen injury updateAllen (hamstring) was questionable to suit up against the Raiders last Thursday, but he did end up seeing the field. However, he played just 24-of-66 offensive snaps,as his hamstring bothered him throughout the night. He was in the game in important situations late, but after failing to connect with Justin Herbert on a red Sandy Alcantara Jersey -zone target, he barely did anything for fantasy owners.Heading into Week 16, Allen's status is unclear. The Chargers have been out of playoff position for a while, however, and Allen has still been playing through the injury, so with 10 days to heal up between games, it's po sible that he will see the field. His practice status this week will go a long way to determining whether he'll play against the Broncos, so that will need to be watched closely this week.WEEK Jorge Alfaro Jersey 16 PPR RANKINGS: | | | | | If Allen can't play, Mike Williams (if healthy), Tyron Johnson, and Jalen Guyton would be the top three receivers for the Chargers. Johnson has come on in recent weeks, so he can be trusted as a worthwhile flex play with upside. Guyton could be picked up, but he's more of a boom-or-bust deep threat, so he's not someone to trust in Deven Marrero Jersey fantasy championship games.WEEK 16 WAIVER WIRE: Stefon Diggs injury updateDiggs suffered a foot injury late in the Bills' blowout win over the Broncos. He exitedand didn't return. The good news is that NFL Network's Kim Jones has reported that Diggs' injury "isn't serious" and "will Kyle Barraclough Jersey not affect his availability going forward."This is great news for Diggs' fantasy owners, as Diggs leads the NFL in receptions (111) and has posted 1,314 receiving yards and five TDs on the year. He will continue to be a top-tier WR and should have a chance to take advantage of the Stephon Gilmore-le s Patriots in Week 16. Trust him as a WR1, and don't worry about his status unle s something changes in the coming days of Bills practice.
