Harper (concussion) is questionable for Sunday's matchup against the Rams, Eric Woodyard of ESPN.com reports.

Harper was a limited participant in all three practices heading into Week 15. The 25-year-old suffered a concussion in the Lions' Week 14 win over Dallas and will need to clear the league's five-step concussion protocol before having a chance to play Sunday against the Rams.

Clowney (hamstring) is listed as questionable for Sunday's game against the Vikings, Adam Caplan of SiriusXM NFL Radio reports.

A hamstring injury prevented Clowney from playing against Detroit in Week 14. He opened Week 15 prep with back-to-back practices before logging a full session Friday, which gives him some positive momentum ahead of Sunday's game. If Clowney is unable to play, then Sam Williams and James Houston would both be in line for larger roles at defensive end opposite Donovan Ezeiruaku.

McCaffrey (illness) doesn't have an injury designation for Sunday's game against the Titans, Cam Inman of The San Jose Mercury News reports.

The 49ers added him to the injury report mid-week due to an illness, but McCaffrey still managed a limited practice Thursday and full session Friday. He should be fine for his usual role this Sunday against the Titans, albeit with higher-than-usual risk of being pulled early from a blowout. Of course, that might be the same scenario in which McCaffrey puts up a ton of points early in the game.

Smith (right shoulder/back) has been ruled out for Sunday's game against the Eagles.

With Smith unavailable, coach Pete Carroll announced that Kenny Pickett will draw the start at quarterback against Philadelphia, Levi Edwards of the Raiders' official site reports. Though Smith didn't practice Wednesday through Friday prior to being ruled out, Carroll said that the veteran signal-caller has "a really good chance to be back next week" against the Texans.

Diggs (knee) is listed as questionable for Sunday's game against Minnesota, Adam Caplan of SiriusXM NFL Radio reports.

Diggs earned the questionable tag for Week 15 after being a limited practice participant all week, but he'll need to be activated from injured reserve in order to play Sunday. He has been sidelined since mid-October after suffering a concussion during a home incident while also working through a knee injury. Diggs' return would likely lead to a reduction in defensive snaps for both Caelen Carson and Shavon Revel.

Lions head coach Dan Campbell said Friday that Joseph (knee) is a possible injured reserve candidate, Tim Twentyman of the Lions' official site reports.

Joseph appeared as a limited participant in practice Wednesday but appeared to have suffered a setback after no participation Thursday or Friday. It looks as though the 25-year-old is set to miss an extended period of time, and it's currently unknown when he will return this season. Thomas Harper will remain as a starting safety in Kerby's absence.

Lassiter (foot) doesn't have an injury designation ahead of Sunday's game against the Cardinals.

Lassiter managed to log a limited practice Friday, his first of the week, and it was enough to clear the cornerback of an injury designation for Sunday's contest. Now that he's past the foot injury he suffered against the Chiefs in Week 14, the cornerback will likely continue the streak of 100 percent defensive snaps he has logged since Week 8.

Washington (concussion) was a limited participant in Friday's practice, Alan Saunders of SteelersNow.comreports.

Washington remains in the concussion protocol but has now logged back-to-back limited practices to begin Week 15. If he's able to practice in full Saturday and gain clearance from an independent neurologist, Washington would be in line to suit up for Monday's matchup against Miami. In the event that Washington can't play Week 15, Jonnu Smith and Pat Freiermuth would stand to benefit slightly from increased target consolidation at the tight end position.

Speed (knee) is listed as questionable for Sunday's game against the Cardinals.

Speed managed to be a limited participant in all practices this week, a positive sign for the linebacker's playing chances. The 30-year-old has not missed a game this season, but if he is not healthy enough to be cleared for Sunday, Jamal Hill and Jake Hansen will likely see increased snaps at outside linebacker for the Texans' defense.

Revel (knee) does not carry an injury designation into Sunday's game against the Vikings, Adam Caplan of SiriusXM NFL Radio reports.

Revel opened the week with back-to-back limited practices due to a knee injury, but the rookie third-rounder has been cleared to play Sunday after logging a full session Friday. He has logged 15 tackles (nine solo) and one pass defense in the four games since the Week 10 bye.
