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.

Harris (hip) doesn't have a designation for Sunday's game in Dallas.

Harris kicked off Week 16 prep with back-to-back limited sessions due to a hip injury, but his ability to get back to all activity Friday has cleared him ahead of the weekend. With Quentin Johnston (groin) listed as questionable again, Harris would be the main beneficiary if the former isn't able to suit up for a second straight contest. In an expanded role this past Sunday at Kansas City, Harris gathered in three of five targets for 49 yards on an 85 percent snap share.

Rice (concussion) has been ruled out for Sunday's game against the Titans.

The same applies to Tyquan Thornton (concussion), which leaves Xavier Worthy, Hollywood Brown and JuJu Smith-Schuster in line to lead the Chiefs' Week 16 WR corps, with Nikko Remigio and Jalen Royals also in the mix. Rice's next opportunity to play will arrive in his team's Dec. 25 contest against the Broncos.

Thornton (concussion) has been ruled out for Sunday's game against the Titans.

Rashee Rice and Thornton both remain in the concussion protocol and won't suit up Sunday after failing to practice in any capacity throughout the week. Thornton would need to log a full practice and receive clearance from an independent neurologist to have a chance to clear protocol before Thursday's game against the Broncos, so he looks like a long shot to play Week 17 as well. Xavier Worthy, Hollywood Brown, JuJu Smith-Schuster, Nikko Remigio and Jalen Royals are the available options at wide receiver for Kansas City this weekend.

Johnston (groin) is listed as questionable for Sunday's game at Dallas.

Johnston sat out this past Sunday's win at Kansas City after he showed up on the Chargers' final Week 15 injury report as limited due to a groin issue. He then had practice restrictions this week before the team tagged him with a designation for Week 16 action. His status ultimately will be confirmed about 90 minutes before Sunday's 1:00 p.m. ET kickoff, but Tre' Harris would figure to benefit again if Johnston is inhibited or sidelined this weekend.

Collins (neck/concussion) has been ruled out ahead of Sunday's matchup against the Vikings, Dan Salomone of the Giants' official site reports.

The Notre Dame product was unable to practice all week, so it's no surprise that he won't return for Sunday's matchup. Collins was designated to return from the injured reserve list Dec. 10, giving him one more week of practice to be added to the Giants' active roster before reverting to IR.

Hardman (calf) is listed as questionable ahead of Sunday's matchup against the Browns.

Hardman returned to practice this week and logged full sessions Thursday and Friday, suggesting he's trending in the right direction ahead of Sunday's contest. However, he must still be added to the Bills' active roster in order to suit up Week 16. If the 27-year-old remains sidelined Sunday, expect Khalil Shakir to handle Buffalo's punt-return duties.
