Things refuse to calm down in the NFL this season, and it seems that every week we see a new wave of injuries that shake up the fantasy landscape.

If you took Adrian Peterson early, you're probably envious of Todd Gurley owners, who still have a chance to trade their struggling first-round pick for someone who will at least be setting foot on an NFL field in the near future. If you were counting on Donte Moncrief to play a big role in your receiving corps, then you have a big gap in your lineup for a few weeks.

Nothing ever goes as planned in fantasy football, and we all need the occasional sleeper to fill a hole in our starting lineup or provide some depth on our benches. Take a look on your waiver wire for these guys, all of whom could make a real fantasy impact.
