The Seahawks host the Packers on Sunday Night Football in a game with big postseason implications for both teams, and Seattle will likely be without starting running back Kenneth Walker III for a second straight game.

Walker, who missed last week's win over the Cardinals with a calf injury, did make progress this week, according to Seahawks coach Mike Macdonald, but he is listed as doubtful after not practicing this week, meaning Zach Charbonnet will likely make a second straight start.

"He hasn't practiced yet, so we've listed him as doubtful," Macdonald said. "That's probably the best way to explain it. Anything can happen between now and the game, but I'd say doubtful right now."

As for Charbonnet, who last week had a career-best 134 rushing yards and two touchdowns, as well as 59 receiving yards, Macdonald just wants to see the second-year back build off of what he has shown so far. The Seahawks will also have Kenny McIntosh, who gained 38 yards on his seven carries last week, and could again elevate George Holani from the practice squad to add further depth.

"Keep building, keep running it tough, taking care of the rock, finishing runs," Macdonald said of his expectations for Charbonnet. "Doing what he does, catching the ball out of the backfield, he's doing a great job in protection, he's done that the whole season. And Kenny Mac and George as well if George is in there instead of Ken."

Tre Brown, who missed last week's game with a hamstring injury, was ruled out, but while he will miss a second straight game, the injury does not appear to be serious enough to merit a trip to injured reserve, Macdonald said.

Also ruled out are safety Jerrick Reed II (quadricep) and tight end Brady Russell (foot) and when Macdonald was asked if either of their injuries were potentially long-term, Macdonald implied a roster move could be coming on one or both, saying, "We'll see on those two guys, maybe make an announcement here in the next day or two on those guys."
