Inside linebacker Brad Jones, who has a hamstring injury, will miss a second straight game.
Coach Mike McCarthy said decisions on James Jones and Neal, who both didn't practice this week, will probably come close to game time. Jones sprained a knee at Baltimore last Sunday.
Coupled with the loss of Randall Cobb, the Packers would be down to Jordy Nelson, Jarrett Boykin and newly added rookie Myles White at receiver if Jones can't play.
The outlook is just as tenuous at outside linebacker, where the Packers are without Clay Matthews and Nick Perry. Rookies Andy Mulumba and Nate Palmer practiced at the position with Neal out.
