Fantasy football can be a fickle beast. One day your team looks unstoppable. The next week your team is being gutted by injuries. The latter part probably happened to a number of teams with close to two dozen players suffering injuries.
With all these injuries, fantasy owners will have to sift through the waiver wire to figure out who to grab because of those injuries. We have you covered, though. Here's a list of the players who went down and how valuable their backup is (arranged by value of replacement within each position):
Quarterback
Robert Griffin III (out 4-8 weeks with an ankle dislocation) - Kirk Cousins is going to start and coach Jay Gruden looks to be a big fan. If you aren't happy with your low-end QB1 in some upcoming matchups, give him a look.
Carson Palmer (should be considered questionable for Week 3) - Drew Stanton started and beat the Giants, but did so without a touchdown. He won't be a fantasy option.
Shaun Hill (day-to-day with a thigh injury) - Austin Davis picked up a win, but his stat line wasn't great with 235 passing yards and no TDs. You have to be extremely desperate to grab him.
Fantasy Advice
Running back
Jamaal Charles (likely out multiple weeks with a high ankle sprain) - Knile Davis is a must-own player in even a two-team league. Go get him and use your No. 1 waiver or most of your FAAB dollars.
Ben Tate (out 2-4 weeks with a knee sprain) - Terrance West hit triple digits in rushing yards in each of the first two weeks. He's a solid RB2 as the starter. Isaiah Crowell is worth a look as a deep-league RB3.
Knowshon Moreno (out 4-8 weeks with a dislocated elbow) - Lamar Miller figures to take over, but he also has a minor ankle sprain. Plus, the Dolphins haven't been too confident with him and even signed Daniel Thomas.
Mark Ingram (out one month with a broken hand) - Khiry Robinson will get plenty of snaps and should see most of the goal-line work.
Dexter McCluster (questionable for Week 3 with an ankle injury) - Bishop Sankey is starting to pick up momentum and his fantasy owners can considering using him after a quiet start to his career.
Ryan Mathews (out 4-5 weeks with a knee sprain) - Donald Brown will share the work with Danny Woodhead. He has a great chance to score three-plus TDs while Mathews is out as the Chargers don't face too many tough matchups.
Doug Martin (day-to-day with a knee injury) - Bobby Rainey is rolling and Martin probably won't be featured after his return. Rainey should be owned in all leagues until further notice.
Maurice Jones-Drew (hand procedure may keep him out in Week 3) - Darren McFadden didn't do much in Week 2, so there's no need to grab him should he still remain on the wire.
DeAngelo Williams (missed Week 2 and could miss Week 3 with a thigh injury) - Jonathan Stewart scored in Week 2 and had 59 yards from scrimmage. Williams isn't expected to be out for long, though.
Joseph Randle (concussion could keep him out for Week 3) - Lance Dunbar was losing snaps to Randle, but who cares when DeMarco Murray is on pace for 2,000 yards?
Wide receivers
Tavon Austin (knee injury will cost him multiple games) - Brian Quick is lapping the field and should be owned in 12-team leagues. Things could also get better when Shaun Hill comes back.
A.J. Green (hopeful to play in Week 3 with turf toe) - He's going to have to play through some pain, but he sounds like a go. Mohamed Sanu would be a great add with Green out. Plus, Marvin Jones is expected to miss another month with his foot injury.
Eric Decker (questionable for Week 3 with a hamstring injury) - Jeremy Kerley will be the man with Decker out. The Jets have a decent schedule, making Kerley a WR3 in PPR leagues for now.
Cecil Shorts III (hamstring injury could keep him out in Week 3) - He hasn't played all season and Allen Hurns busted out in Week 1. However, he caught just two balls for 13 yards in Week 2. The Jaguars are not good.
Rod Streater (hip problem and could miss time) - James Jones is maximizing garbage time and has put himself into the WR3 conversation.
DeSean Jackson (questionable for Week 3 with AC joint injury) - Andre Roberts looked good with 57 receiving yards in Week 2, but he's not a strong enough replacement to grab in fantasy, especially since DeSean's injury is not serious.
Tight ends
Jordan Reed (hamstring issue makes him unlikely for Week 3) - Niles Paul was awesome with 99 receiving yards and one score. He's a strong TE2 right now.
Tyler Eifert (dislocated elbow could keep him out until Week 1) - Jermaine Gresham should flirt with TE1 value, especially if A.J. Green is out.
Austin Seferian-Jenkins (could be back for Week 3 from his foot issue) - Brandon Myers caught two balls in Week 2. He's a desperate TE2 with a low ceiling.
Vernon Davis (will have an MRI for his ankle injury) - Derek Carrier could be integrated into the offense, but he's a risky TE2 in deep leagues.
Jordan Cameron (shoulder injury is a week-to-week concern) - There is no backup to pick up here.
Marcedes Lewis (out 6-8 weeks with an ankle injury) - Jaguars.
