Davis (ankle) has been ruled out for Sunday's matchup against the Cowboys.

After not practicing all week, Davis will miss his second straight game due to an ankle injury that he suffered in Week 14. The 25-year-old operates as the team's primary kick returner. While he is out, KeAndre Lambert-Smith and Ladd McConkey are expected to take on a bigger load as kick and punt returners, respectively.

Harrison (heel) is listed as questionable for Sunday's game against the Falcons, after telling reporters Friday that he expects to play, Bo Brack of GoPHNX.com reports.

Harrison was a limited practice participant Wednesday through Friday, saying afterward that he's "good enough to go" this Sunday. He also said his heel injury is unlikely to resolve before the end of the season, but he thinks he'll be able to play through it in Weeks 16-18 after missing the past two games. In light of the 'questionable' designation, Arizona's late-afternoon kickoff (4:05 p.m. ET) is suboptimal for fantasy managers, with Harrison's availability taking on extra importance due to the impact on Michael Wilson's projection.

Tipton (illness) is listed as questionable for Sunday's game against the Jets after missing practice Thursday and Friday, Ross Jackson of WWL Louisiana reports.

With Devaughn Vele (shoulder) recently placed on injured reserve, Tipton has a chance to step up as the Saints' No. 2 WR over the final three weeks of the season. If he can't play Sunday, the Saints will turn to Dante Pettis and Kevin Austin -- both of whom figure to have roles even if Tipton is active.

Smith secured both of his targets for 57 yards and returned one punt for 31 yards during Thursday's 38-37 overtime loss to the Seahawks.

On a third-and-9 play early in the third quarter, Smith was able to burn past Devon Witherspoon and snag a dart from Matthew Stafford for a 48-yard gain, leading to a Harrison Mevis field goal a few plays later. Smith has shown the ability to make explosive plays when called upon in recent weeks, including a 51-yard catch in Week 13 against Carolina. Fellow backups Jordan Whittington and Tutu Atwell combined for a single catch for 19 yards, while Konata Mumpfield earned a whopping eight targets, which he turned into three catches for 40 yards. If Davante Adams (knee/hamstring) isn't able to go for a Week 17 matchup in Atlanta on Monday, Dec. 29, Mumpfield and Smith seem like the primary candidates for a role increase behind Puka Nacua.

Nailor (back) doesn't have an injury designation for Sunday's game against the Giants.

He figures to fill his usual role as the Vikings' No. 3 receiver, coming off a two-TD showing at Dallas in Week 16. Nailor returned to full practice participation Friday after limited sessions earlier in the week.

Pierce (Achilles) was a full participant at Friday's practice.

Pierce was listed as limited Thursday, but his limitations appear to have been precautionary after he played every snap on offense in this past Sunday's loss to the Seahawks. Barring a setback, Pierce won't have an injury designation for Monday's game against the 49ers when the Colts release their injury report Saturday.

Higgins (concussion) was a full participant in practice Friday but is listed as questionable for Sunday's game against the Dolphins.

Higgins upgraded to full participation after a pair of limited practices, which marks another step forward as he works his way through the NFL's five-step concussion protocol, but he still needs to earn clearance from an independent neurologist before he can play again. If Higgins is cleared, the star wide receiver would likely return Sunday after missing his team's Week 15 loss to the Ravens. Either way, since the Bengals kick off Sunday at 1:00 p.m. ET, those considering Higgins in Week 16 fantasy lineups will have his playing status confirmed before the first wave of games that day.

Jefferson (back) practiced fully Friday but is listed as questionable for Sunday's game against the Chiefs, Jim Wyatt of the Titans' official site reports.

Jefferson trended in the right direction throughout the week, going from a non-participant Wednesday to limited Thursday before Friday's full session. The veteran wide receiver's status likely won't be confirmed until 90 minutes prior to Sunday's 1:00 p.m. ET kickoff. Jefferson has 24 catches for 280 yards and a touchdown in 14 appearances this season, averaging exactly 20 receiving yards per game.

Olszewski (concussion) has no injury designation ahead of Sunday's matchup against the Vikings, Dan Salomone of the Giants' official site reports.

The 29-year-old practiced in full throughout the week and has now cleared the NFL's five-step concussion protocol, allowing him to return for Sunday's matchup. Now fully healthy, Olszewski is expected to operate as the Giants' top kick and punt returner in Week 16.

Harrison (heel) said he's "good enough to go" for Sunday's game against the Falcons, Bo Brack of GoPHNX.com reports.

Harrison may still have an injury designation but apparently expects to play. He was a limited practice participant Wednesday and Thursday, after missing the past two games with a heel injury.
