The Packers are already without the top touchdown maker in Jordy Nelson (ACL) and starting middle linebacker Sam Barrington (foot), and they'll now host the Seahawks without starting right tackle Bryan Bulaga.
Bulaga went out of practice on Thursday with a knee injury, and the team apparently feels it's serious enough to have declared him out for Sunday.
"Bryan Bulaga suffered a knee injury," Packers head coach Mike McCarthy said Friday. "He will be out this week. He is still going through the evaluation process, but he will not play in Sunday night's game."
Bulaga started 14 games for the Packers last year (plus two in the Playoffs) but has a history of knee injuries -- he missed two games with an MCL strain suffered against the Seahawks in Week 2, and he blew out his knee in 2013.
