PThe injuries never stop for fantasy football owners, and heading into Week 4, there have been a few "surprises" popping up on the practice injury updates. Amon-Ra St. Brown, Cordarrelle Patterson, and Gabe Davis are among the key fantasy contributors who have mi sed time this week, and all will cause plenty of waiver wire activity and start 'em, sit 'em panic if they're ruled out ahead of Sunday's games.Below, we'll give you the latest news on these players and break down how their Roger Maris Jersey injuries could potentially affect the Week 4 fantasy landscape. For updates on ailing pa s-catchersChris Godwin,Keenan Allen,Dalton Schultz,Michael Thomas,Julio Jones, andJakobi Meyers,; for more on banged-up RBs Whitey Herzog Jersey Dalvin Cook,David Montgomery,D'Andre Swift, andChristian McCaffrey,.WEEK 4 FANTASY PICKS: | | UPDATE:St. Brown is officially OUT for Week 4.St. Brown injured his ankle in last week's game against Minnesota, but after getting it taped up, he returned and finished the contest. However, as is often the case, he's experiencing some residual sorene s the following week, and he's now ahead of Sunday's favorable matchup vs. the Seahawks.It's po sible the Lions are just being extra cautious with their young star, so if he returns to practice on Friday, he should be in good shape to play. Nonethele s, he'll be listed as at least "questionable," so he'll remain a concern until Sunday morning. If he's out, give DJ Chark and Josh Reynolds big bumps up in value (though Chark is dealing with an ankle injury of his own), as both can work as flexes.WEEK 4 PPR RANKINGS: | | | | | UPDATE:Patterson practiced Tim McCarver Jersey on a limited basis on Friday and is officially OUT for Week 4.Patterson (knee) , and while the Falcons are listing him as "resting," it's still a cause for concern heading into Sunday's game against the Browns.Patterson has been a workhorse for the Falcons early on, carrying the ball 49 times and adding another four receptions. He's must-start when active, but if he can't go, Tyler Allgeier will take over and likely see 15-plus touches. That's enough to make him an RB2/flex despite a relatively tough matchup.WEEK 4 STANDARD RANKINGS: | | | | | UPDATE: Harrison Bader Jersey Davis got in a limited practice on Friday and is officially "questionable" for Week 4.Davis, who sat out Week 2, because of the ankle i sue that's been bothering him the past two weeks. It's po sible this is just a rest day for the rising star, but clearly it's an i sue ahead of a highly favorable matchup in Baltimore.WEEK 4 DFS LINEUPS: | If Davis suits up, he's a must-start despite the injury. If he's out, it's reasonable to give Isaiah McKenzie a bump up in value, though neither McKenzie nor Jamison Crowder was able to take advantage of Davis' absence in Week 2. Kolten Wong Jersey TE Dawson Knox might actually be the biggest beneficiary in the form of increased targets in the red zone.
