The Packers are still determining how much time Graham will miss.
The tight end exited in the first half against Seattle and missed the remainder of the game.
Graham was one of Green Bay's biggest offseason additions, signing a three-year, $30-million contract in March.
The five-time Pro Bowler ranks second on the team in receiving this year with 34 catches for 452 yards and two touchdowns.
The 4-5-1 Packers will next face the Minnesota Vikings in Week 12.
