Kenneth Walker III is back, but four defensive players are out for the Seahawks' Week 4 game at Detroit

Mafe, who leads the team with 3.0 sacks, initially injured his knee in Seattle's Week 2 win over the Patriots and was able to play against Miami last week, but something happened with that injury that has left him unable to play this week will exclude.

“I don't want to get into specific plays and all that, but it's nothing major, something came up again in the Miami game that kept him from playing that game,” Macdonald said.

Of Walker, who ran for 103 yards in Week 1 before exiting late in the game with an oblique injury, Macdonald said: “He looked good. He’s ready to go.”

Macdonald added that with the return of Walker and Zach Charbonnet, the Seahawks get “the duo that you've had all season and what you envisioned our offense to be like, and then when one's out, that's when guys like Kenny McIntosh step up.” and can take on these roles.

The Seahawks got an extra day of work this week. Despite playing a game on Monday, they began with their usual practice on Wednesday and Thursday and then broke up the training week with a walkthrough speed practice on Friday before holding their normal Friday practice on Saturday. Macdonald said the schedule was put together primarily with Monday's game in mind, but also with two straight short-rest games in mind, starting with next Sunday's game against the Giants, followed by a Thursday night game against the 49ers.

“That's exactly where we find ourselves over the course of the year, doing the installations, starting our normal work week and then trying to get a day of recovery and thinking ahead to what best enables us to “To be prepared for it.” Monday night, and after that we have a few games on top of each other,” he said. “So it’s a combination of short-term and long-term.”
