One thing I've learned from writing about sleepers week in and week out during NFL sesaon for the past year and a half is that the term can really mean whatever you want it to mean -- provided that it's not just recommending super obvious plays.

Players who have been slumping? Sleeper potential. Players in bad matchups, games with low over/unders, or who aren't getting much usage? Sleepers.

But there are also a lot of players who get forgotten about pretty quickly in the fantasy world after being injured or having a bye -- or both.

Whether the following guys are stepping into larger roles because of injuries or reports of more work heading their way -- or they're just in great matchups -- they can help plug the bye-week and injury gaps in your fantasy lineup or help round out a tournament roster in a daily fantasy tournament.
