According to the team's injury report, TE Zach Miller has been ruled out after missing practice all week with a "Neck/Head" injury. It's hard to know exactly what the problem is, given the vagueness of the description in the report, but Miller's had two weeks to heal up and he still isn't right. That's not good.
Miller being sidelined also means that the only tight end currently on the active roster is Anthony McCoy, who is a much better blocker than he is a receiver. If the Seahawks decide to add another TE to pair with McCoy, they do have some options close at hand. Since we're past the week six mark, Cameron Morrah is eligible for activation off the PUP list, or if he's not fully healthy then practice squadder John Nalbone could be promoted to the active roster instead. Another possibility could be receiving TE Dominique Byrd, who remains a free agent after being cut by the Seahawks back in week two.
To make matters worse, C Max Unger is listed as doubtful. Unger's solid performance has played a big part in the success of Seattle's no-huddle offense the last few games, and if he ends up sidelined then backup C/G Lemuel Jeanpierre will likely start in his place. Jeanpierre is a second-year man with just a handful of snaps to his name this season, so there's no telling how comfortable he's going to be making calls for the o-line.
Tarvaris Jackson is listed as doubtful, which is unfortunate given his command of the offense the last few games, but Charlie Whitehurst proved the Seahawks could win with him under center when he replaced Jackson toward the end of the game against the Giants. Far better to let Whitehurst play than rush Jackson's return and risk worsening his injured pectoral.
On the bright side, Robert Gallery appears to have recovered from his groin surgery and is listed as probable to play this week. That's great news -- I don't know about the rest of you, but I've seen all I want of Paul McQuistan and his questionable strength. Also probable this week are Mike Williams, Malcolm Smith, and Marshawn Lynch.
