The Packers (4-4-1) left for the Pacific Northwest to face the Seahawks (4-5) without wide receiver Randall Cobb, safety Kentrell Brice, cornerback Kevin King and linebacker Nick Perry. Their expected absences, according to ESPN, are related to their rehabilitation schedules from their respective injuries.
Cobb sat out last week's 31-12 win over the Miami Dolphins after sustaining a setback in practice during his recovery from a hamstring injury. He also sat out practice on Monday and Tuesday.
The 28-year-old has 26 receptions for 258 yards and one touchdown in five games this season. He is four years removed from a Pro Bowl campaign in 2014, when he collected 1,287 receiving yards and 12 scores.
Brice, who was seen in a walking boot this week, has collected 33 tackles and one sack in nine contests in 2018.
The 23-year-old King, who is nursing an undisclosed injury, has recorded 17 tackles and an interception this season.
Perry, who sustained a knee injury against the Dolphins, has 24 tackles and a forced fumble in 2018.
