It wouldn't be an NFL season without injuries, but the level of skill-position injuries happening in the first two weeks of the 2016 season is pretty concerning.

Sunday alone saw seven different running backs dealing with things ranging from minor to extremely major injuries.

We've seen some updates to those teams as well as some players added to the pile, so let's run down some updates on these key players.

1. Ameer Abdullah, RB, Lions

Another promising season fell short for the hyper-talented back out of Nebraska. Expected to break out in his sophomore season, Abdullah posted a big first week of the season (120 yards, one score) and started off strong in his second week (6.33 yards per carry) before leaving with a foot injury. The Lions placed him on injured reserve Wednesday morning, potentially ending his season. Abdullah could return after some time (designated IR) but it sounds like his season is done.

Fantasy Spin: Theo Riddick now becomes the guy in Detroit and could be a monster in PPR leagues. Rookie Dwayne Washington is someone worth picking up immediately as well (he could be the goal line beneficiary) and Zach Zenner is a solid add in deeper leagues just because he could be the next man up.

2. Jay Cutler, QB, Bears

Some good news on this front, as it appears Cutler won't need surgery on his right thumb. John Fox is calling him "day-to-day," which is really a nice way of saying "I'm kind of mad our quarterback is hurt and this injury is going to linger but I have no idea how long, so please stop asking me about it." The expectation is he'll miss two-to-three weeks (the Bears play the Cowboys, Lions, Colts and Jaguars over the next four weeks) but the timeline could move drastically depending on how Cutler heals over the next few days, according to

Fantasy Spin: Brian Hoyer is a decent add in two-quarterback leagues with that schedule if you're desperate. Alshon Jeffery takes a hit here but you're still starting him. Kevin White is probably careening towards drop territory if you haven't, although the Bears seem desperate to feed him. This is a bad team quickly getting worse.

3. Doug Martin, RB, Buccaneers

The Dougernaut (a.k.a. The Muscle Hampster) is going to miss three weeks with a hamstring strain according to Ian Rapoport of NFL Network.

After an All-Pro season last year, Martin struggled out of the gate for the Bucs this year, averaging just 3.4 yards per carry and 42.5 yards per game against the Falcons and Cardinals.

Fantasy Spin: Charles Sims gets a big bump here and could turn into a strong play over the next few weeks, especially in PPR leagues (he was already a borderline FLEX starter because of his pass-catching skills). The only problem? The Bucs get the Rams, Broncos and Panthers before a Week 6 bye. That's a brutal schedule for a running back, although we could see lots of dump downs from Jameis Winston too.

4. Rob Gronkowski, TE and Jimmy Garoppolo, QB, Patriots

Two pretty critical players here for New England. Gronk was limited in practice this week and could potentially return against the Texans on Thursday. It's also possible the Pats decide to give him another 10 days of rest before putting him on the field. Garoppolo's time frame from an AC joint injury keeps shrinking -- he was going to be out six weeks, then it was two weeks, then it was one and now it's maybe one. He could potentially play depending on how he feels, although it could be a ploy by the Pats to make the Texans prepare for two quarterbacks.

Fantasy Spin: Jacoby Brissett will be better than people expect, but you probably can't start him in fantasy. He did target Martellus Bennett frequently when he came in with Gronk out, so Bennett is an interesting play this week regardless.

5. Adrian Peterson, RB, Vikings

The Vikings are preparing to play this week at Carolina without Peterson, according to Ed Werder of ESPN. Peterson suffered a torn meniscus during Sunday night's win over the Packers, although he hasn't been particularly effective this year regardless.

Fantasy Spin: Jerick McKinnon and Matt Asiata are the guys who will get carries, but the number each gets is totally up in the air. McKinnon is a more explosive player, but he's not necessarily a three-down back because of pass protection. Asiata should see the goal-line carries for this squad. Neither are great plays considering the Panthers stout defense.

6. Danny Woodhead, RB, Chargers

The do-it-all grit-meister is done for the year with a torn ACL. Life remains completely unfair for Philip Rivers, who has now lost two of his top playmakers in consecutive weeks to an ACL (Keenan Allen in Week 1). The Bolts signed Dexter McCluster as a free agent.

Fantasy Spin: Melvin Gordon is suddenly a stud. Hold him or buy him if you can. He's going to get a huge workload, and if he produces the way he has this season so far, he could end up as a top-10 fantasy running back ... or higher. McCluster is an interesting option in PPR leagues and leagues that offer return yardage. Rivers loves using his running backs in short-yardage situations and McCluster has familiarity with OC Ken Whisenhunt's system.
