Several key wide receivers (Amon-Ra St. Brown, Keenan Allen, Michael Thomas) failed to suit up this past Sunday, and their statues for Week 5 are up in the air. Knowing these key WR's latest injury updates is crucial before finalizing your waiver wire pickups and Week 5 start 'em, sit 'em decisions.Below, we'll give you the latest news on these receivers and break down how their injuries could potentially affect the Week 5 fantasy landscape. For news on banged-up RBs Brian Robinson,Alvin Kamara,David Montgomery, D'Andre Swift,;for the latest on ailing RBsJonathan Taylor,Cordarrelle Patterson, andJavonte Williams,; for more updates on injured WRs, likeIsaiah McKenzie,Jahan Dotson, andTreylon Burks,.WEEK 5 FANTASY: | |St. Brown (ankle) got banged up in Detroit's 28-24 Week 3 lo s to Minnesota and then failed to practice the week ahead of the Lions' Week 4 matchup against Seattle prior to being ruled "out" on Friday. In his absence, fellow Lions' pa s-catchers Curtis Granderson Jersey T.J. Hockenson, Josh Reynolds, and Tom Kennedy saw increased roles in the offense, with Hockenson leading all Lions in receiving (eight receptions, 179 yards, two TDs).We'll get a better feel for St. Brown's Week 5 status once the Lions release their initial injury report on Wednesday. Should St. Brown return to practice on Wednesday, he looks to be on track to make his return to the field for the Lions' Week 5 road tilt in New England. St. Brown remains a WR1 in both standard and PPR formats.WEEK 5 STANDARD RANKINGS: | | | | | Allen (hamstring) mi sed his third straight game dealing with a hamstring injury that he suffered in Los Angeles' Week 1 matchup against Las Vegas. Allen returned to practice this past week but aggravated the injury. Head coach Brandon Staley called Allen on Monday, and it's unclear whether he'll returnin Week 5.If Allen were to mi s his fourth straight game, fellow pa s-catchers Mike Williams and Gerald Everett remain must-starts, and Josh Palmer remains a borderline WR3. If Allen does return, Williams and Everett should be in fantasy manager's starting lineups regardle s, while Palmer is likely relegated to the bench.WEEK 5 PPR RANKINGS: | | | | | Thomas (toe) mi sed the Saints' 28-25 win over Minnesota in London after failing to practice throughout the week.We still don't know if Thomas will be ready to go for Week 5 against the Seahawks, but if he's able to practice in a limited fashion, he has a shot. If Thomas can't go for a second-straight week, WR Chris Olave remains a must-start, but you can't really trust any of New Orleans' other options, especially given the Saints' QB I sues right now.
