@AlbertBreer: From @RapSheet and I — In addition his sprained MCL, Packers OT Bryan Bulaga also needs meniscus repair. Could be out a while.
The Packers did not think it was serious but Bulaga required surgery. The Packers apparently discovered the meniscus tear after running more tests on his knee.
Thankfully the ACL is still in place, but the Packers will miss the solid tackle.
