GREEN BAY, Wis. – The Green Bay Packers could be getting several key players back for Sunday night’s game at the Seattle Seahawks.

For the second consecutive day, safety Javon Bullard was the only member of the active roster who did not practice on Thursday.

Cornerback Jaire Alexander, who has missed three consecutive games with a knee injury, was full participation for a second consecutive day.

Receiver Romeo Doubs, who missed the last two games, and safety Evan Williams, who was injured during the first half at Detroit, practiced again as they work their way through the concussion protocol.

Both were full participation on Thursday. While both players remain in the concussion protocol, coach Matt LaFleur said after practice, their participation status at practice would seem to be good news in advance of Sunday night.

Plus, linebacker Edgerrin Cooper provided a big update on his status.

Alexander originally was injured on the final defensive snap at Jacksonville on Oct. 27. He has played just 10 snaps since – at Chicago after the bye, when he aggravated the injury.

“I’m feeling better. Feeling better. It’s a process,” Alexander said after practice.

His presence would be important this week against the Seahawks’ high-flying passing game. Quarterback Geno Smith is second in the NFL in completions, attempts and yards.

“When Ja is healthy, he’s one of the best corners in our league,” defensive coordinator Jeff Hafley said. “Week in and week out, when you’re playing against some premier players, sometimes it’s helpful to have a premier player to have out there with him.”

Receiver Dontayvion Wicks, who was shaken up on the final series at Detroit, and cornerback Corey Ballentine, who injured a knee on the opening kickoff return against Miami and was out at Detroit, practiced, as well.

Second-year tight end Luke Musgrave, who was designated to return from injured reserve on Wednesday, practiced for a second consecutive day.

During the portion of practice open to reporters, he worked on blocking drills with an assistant coach while the other tight ends went through a routes-on-air period with the quarterbacks and receivers.

“It’s been awesome to see Luke,” quarterback Jordan Love said on Wednesday. “He was out there in pads and what not doing some individual stuff today. It was great to see him back here. Obviously, had a tough injury, didn’t know when he was going to be back, if it would be this week or not. It’s definitely nice to see him back out there.

“Hopefully, we can get him back for the end of the season and for playoffs and what not, so it’s awesome to have a guy like that back out there.”

Defensive tackle Kenny Clark and guard Elgton Jenkins were added to the injury report but only for rest.

Seattle has a long injury report, but many of those players were out on Wednesday while getting veteran rest.

One key player who did not practice on Wednesday or Thursday was standout running back Kenneth Walker due to a calf injury that held him out last week. Not only is Walker the team’s leading rusher with 542 yards and seven touchdowns, but he’s also set career highs with 38 receptions for 271 yards.

“He’s still day-to-day right now,” Seahawks coach Mike Macdonald told reporters in Seattle on Wednesday. “I wouldn’t say a lot more. It got more complicated as the week went on, so that’s why we had to do some more tests and stuff. But right now, there are positive signs. So, we’ll just say day-to-day I think is fair, but it’s not long term.”

In 40 games in three seasons, Walker has 3,192 total yards and 26 touchdowns.

He wouldn’t necessarily need to practice to play in the game.

“I would like to see him at some point,” Macdonald said, “but I wouldn’t say that that would exclude him from playing.”
