D’Andre Swift Injury Outlook

D’Andre Swift reportedly suffered a sprained shoulder in the Lions’ loss to the Vikings on Sunday and per Tom Pelissero on Twitter, the injury is not expected to need surgery, however, he may miss some time. (Source: Tom Pelissero on twitter)

Fantasy Impact: Swift had a rather subpar fantasy line coming out of the Lions’ Week 3 matchup against the Vikings, it is now more clear that the Lions were just taking the cautious approach with their star back. The 23-year-old may miss some time now with the shoulder injury, thankfully he will not need a surgery to repair his shoulder, he did also re-injure his ankle in the process so managers should monitor his practice reports this week. If the Georgia product is a no-go it will be Jamaal Williams receiving the bulk of the work, which would launch Williams into the RB3/Flex range.

Waiver Wire Replacements to Target

Khalil Herbert (RB – CHI): 49% rostered

• Next opponents: @NYG, @MIN, WAS
• True value: $23
• Desperate need: $39
• Budget-minded: $9

Analysis: The best time to acquire Khalil Herbert was any of the previous three weeks when I ranked him as the best handcuff-with-standalone-value in fantasy. You can still get him in half of Yahoo leagues, but his Tuesday price tag will be substantial. David Montgomery suffered multiple lower-body injuries on Sunday and did not return. His “backup,” Herbert, took the bull by the horns and dropped a huge fantasy performance on the Texans, with 20 carries for 157 yards and two touchdowns. The schedule is also very manageable for the Bears for a few games. I see Herbert as the top priority waiver claim for Week 4.

Alexander Mattison (RB – MIN): 55% rostered*

• Next opponents: @NO, CHI, @MIA
• True value: $9
• Desperate need: $23
• Budget-minded: $5

Analysis: The caveat here is that Mattison is over the typical 50% threshold to grace this column, but Dalvin Cook‘s shoulder injury has activated Mattison managers like the Undertaker. Cook has a long history of shoulder injuries, and there have been times when he’s sustained one and didn’t even miss the next game. If that’s the case and Cook is active in Week 5 but on a snap count, it would be very tough to pull the trigger on starting Mattison. The risk is massive. Either Cook plays full snaps and renders Mattison completely unusable, or Cook is limited and Mattison is cooking on your bench. If Cook misses any games, Mattison is a premium handcuff with RB2 upside.

Trestan Ebner (RB – CHI): 0% rostered

• Next opponents: @NYG, @MIN, WAS
• True value: $3
• Desperate need: $5
• Budget-minded: $1

Analysis: Ebner might be just a stash to many fantasy managers, but I might want to toss a couple of extra FAAB dollars to get him as a short-term PPR weapon. If David Montgomery is out for an extended amount of time, the Bears will likely be forced to increase Ebner’s snap share and touches. Ebner is a strong receiver with incredible speed and quickness. Let’s call him a stash-plus.
