I'm sure Thursday is a travel day to Arizona for Friday's game against the Cardinals. Mike McCarthy said QB Matt Flynn, LB Clay Matthews, and LB Nick Barnett are doubtful for the game, which in preseason means they're out. A few others won't play either, from Tom Pelissero:

That's in addition to the list of players who didn't suit up once this week and won't play against the Cardinals: CB Pat Lee (back), S Aaron Rouse (hamstring), DE Justin Harrell (back), S Charlie Peprah (knee) and CB Will Blackmon (quad).

During the Wednesday itself practice, the backup linebackers continued to impress. First LB Brandon Chillar, and then LB Brad Jones.

When they ran the 4-3 defense last season, they usually only kept five linebackers on the roster. But as Green and Bold predicted, they might keep as many as nine on the 53 man roster this season. At first, that seemed like too many, but players like Aaron Kampman, Clay Matthews, Brady Poppinga, and Jeremy Thompson might all be asked to play at defensive end in a 4-2-5 alignment on passing downs, so they are providing depth throughout the entire defensive front seven.
