Injuries: Luke Kuechly not yet back from concussion

The Carolina Panthers look as though they'll be without star linebacker Luke Kuechly another week.

Kuechly sustained a concussion in a season-opening victory over the Jaguars and missed last week as a result of it. He returned to practice without a helmet and hasn't participated in team drills. That leaves him unlikely to play in Sunday's NFC South matchup against the winless Saints.

At least the Panthers got some good news about Star Lotulelei. The defensive tackle practiced Thursday and could be back on the field Sunday. He missed the first two games of the season after suffering a stress reaction in his right foot during training camp.

Here's the rest of Thursday's notable injury news:

1. Packers running back Eddie Lacy is improving, but not quite ready for Monday night's matchup with the Chiefs. Lacy suffered an ankle injury in last weekend's win over the Seahawks, which prompted him to leave the game. Wideout Davante Adams also missed the first two practices of the week with an ankle injury and is in a similar position as Lacy.

"I think the last three days helped our whole football team," Packers coach Mike McCarthy said before Thursday's practice. "Eddie and Davante have been here pretty much most of the day, most of the three days. They're getting better. They'll both do some pre-practice work and then we'll see from there, but I don't have high expectations of them practicing today."

2. DeMarco Murray tweaked his hamstring at Wednesday's practice, Eagles coach Chip Kelly said. He's had a hard time in the first two weeks, totaling less a yard per carry so far this season. The team is unsure he will play Sunday against the Jets.

Another blow for the Eagles, linebacker Kiko Alonso will likely miss Sunday's game against the Jets, according to Kelly.

3. Saints quarterback Drew Brees was limited in practice Thursday, and he hasn't been ruled out for Sunday. Coach Sean Payton said they'll take things a day at a time, and Brees said he's "pretty confident" he'll play Sunday against the Panthers as New Orleans tries to avoid the unenviable 0-3 start.

In addition to Brees, cornerback Keenan Lewis (hip) was also limited for the Saints.

4. Ravens wide receiver Breshad Perrimanpracticed for the first time since July 30th. He still looked tentative, which is understandable given that he hadn't practiced in eight weeks with knee injury, according to the Baltimore Sun.

5. Texans running back Arian Foster (groin) doesn't have a timetable on his return yet but said, "I feel wonderful." He also said his groin is "not 100" yet. "I'm going to make sure I'm 100 percent so I'm not jeopardizing myself or my teammates," he continued.

6. Jets cornerback Darrell Revis (groin) and wideout Eric Decker (knee) both returned to practice wearing helmets after missing Wednesday's practice. Coach Todd Bowles said he's "hopeful he will play" this Sunday against the Eagles.

Wideout Chris Owusuhad his knee scope Thursday. He is expected to miss at least three weeks.

Running back Chris Ivory (quad/groin) could be a game-time decision.

7. Dolphins tight end Jordan Cameron (groin) was limited in practice after not practicing Wednesday. He was doing drills in a helmet.

8. Bengals wideout A.J. Green was back at practice after missing Wednesday with a knee injury. That's promising news for the Bengals, who hope to move to 3-0 with a win over the division rival Baltimore Ravens.

9. Rams rookie running back Todd Gurley said he's ready to play after missing the first two weeks of the season. Gurley knows it is up to the coaches but he feels optimistic about his chances to see his first NFL action.7

10. Alshon Jeffery is not practicing for the Bears, but fellow wideout Eddie Royal is, according to NFL Media's Stacey Dales. Jeffery missed last week's game with a hamstring injury while Royal is recovering from a hip injury.

11. Vikings guard Brandon Fuscomissed practice Wednesday with a concussion. His availability for Sunday's game against the San Diego Chargers remains uncertain.

12. Colts cornerback Vontae Davis (concussion) has been cleared to play. He was practicing without a red jersey.

13. Jaguars coach Gus Bradley said right guard Brandon Linder (shoulder) is 50-50 for Sunday vs. Patriots. Linder is a starting lineman.

Running back Toby Gerhart (abdomen) worked out full and wideout Allen Hurns (thigh soreness) was limited at practice.

14. Ravens offensive tackle Eugene Monroe (concussion) and running back Lorenzo Taliaferro (foot) did not practice Thursday. Wideout Breshad Perriman (knee), who was held out of practice Wednesday, returned in a limited role on Thursday.

15. Dolphins defensive tackle Earl Mitchell (back) and Branden Albert (hamstring) both missed practice. Starting running back Lamar Miller (ankle) was limited but Cameron Wake was a full participant after being limited Wednesday.

16. Saints wideout Brandin Cooks is "very confident" he'll play Sunday despite an ankle injury.

17. Receiver Julio Jones (hamstring) was limited in practice for the Falcons and linebacker Brooks Reed was able to practice after a groin procedure caused him to miss the first two weeks of the season.

18. Defensive end Ziggy Ansah (back) was limited in practice and tight end Brandon Pettigrew sat out with a sore hamstring, again.

19. Linebacker Jon Beason (knee) was active for the Giants in their victory over the Redskins on Thursday.

20. Tight end Jason Witten (ankle, knee) was limited at Cowboys practice the second straight day, but is expected to play Sunday.

21. Raiders safety Charles Woodson (shoulder) and defensive end Justin Tuck (knee) returned to practice.

22. Running back Marshawn Lynch (calf) was limited for Seattle on Thursday. Lynch's injury is not believed to be serious.

23. Chargers guard D.J. Fluker (ankle) returned to practice on a limited basis on Thursday. Fluker was carted off the field Week 1 against the Lions.
