Pickett and Saine suffered concussions against the Raiders. This is Pickett's second concussion this year, which is probably informing the Packers decision to hold him out this week.
Mike McCarthy told reporters this afternoon that James Starks was limited in what he did at practice today, which was mostly individual work, and that they would give him up until the game on Sunday to determine if he can go. With Saine's availability in doubt, this could cause a potential problem at the running back position, although the team would probably just use John Kuhn more in his running back role and use Tom Crabtree and Ryan Taylor more at fullback for certain formations.
On a more positive note, McCarthy said he though Josh Sitton "looked fine" and that they would know more tomorrow. If Sitton is unable to go, Evan Dietrich-Smith would get his third start in a row at right guard.
One final injury note, McCarthy indicated that tight end Andrew Quarless had not yet had surgery on his knee, which he injured in the game nearly three weeks ago against the Giants. McCarthy said he thought Quarless, who the team has placed on injured reserve, would have the surgery sometime in the next week. The team has still not said exactly what the injury is, but Bob McGinn of the Milwaukee Journal Sentinel has intimated that Quarless' availability for 2012 may be in question.
