Reid was one of three casualties during the Lions' defensive line cleanup, joining George Johnson and Datone Jones. The difference is Reid was actually drafted by Detroit in 2014, but he hasn't produced much over the past four seasons and won't be an IDP threat with his next team.
Maxwell was last active for a game in Week 2 against the Jets, where he notched four solo tackles and a forced fumble. When he's healthy, he plays nearly a full snap count, and if he can rack up more tackles, Maxwell will develop into a solid IDP option.
Jones didn't re-sign with the Packers after the 2016 season, and he then signed on with the Vikings, who waived him with a shoulder injury in September. He stuck with the NFC North, though, and signed with the Lions just over a week ago, but his term in Detroit was short lived. The Bears don't look like they're in the market for a defensive end, so he'll likely stray outside of the division for the first time in his career five-year career.
Johnson actually played a fair amount on the Lions' defensive front, logging 81 snaps over four games. Still, the Lions opted to bring in Jacquies Smith instead, leading to Johnson's departure.
After being let go by the Bucs two weeks ago, Smith has found his new home. He hasn't played significant snaps since he logged 546 defensive snaps in 2015, though, and he likely will be used sparingly in Detroit as well.
The undrafted rookie is in line to make his season debut against the Vikings on Sunday. Hill was expected to be used as a reserve cornerback with special teams upside, but with the injuries in Baltimore's secondary, he may find some defensive snaps.
Davis missed just one game with this injury, but he's on pace to place Sunday in Minnesota. The third-year nose tackle hasn't been consistently playing enough snaps to be a fantasy threat, though, so don't consider him an IDP threat at this time.
Williams injured his elbow in Week 5 against the Bills but evidently returned to full health during the Bengals' Week 6 bye. He appears all set to man his usual starting spot at strong safety Sunday.
It seems Garrett has fully recovered from his high-ankle sprain that forced him to miss the first four weeks of the season. The rookie leads the Browns with three sacks and will look to add to that total Sunday versus the Titans.
Shelton is dealing with an ankle injury after just recently healing from a calf ailment that forced him to sit out in Week 4, but the fact he practiced in some capacity Wednesday means his new affliction isn't considered serious. Expect him to be out there versus the Titans on Sunday.
