Hold on to your butts!
Seahawks inactives: Percy Harvin, Christine Michael, Michael Bowie, Caylin Hauptmann, O'Brien Schofield, Benson Mayowa and Jordan Hill.
The big surprise here is that OG Michael Bowie is inactive, which means James Carpenter (and/or perhaps Paul McQuistan) will get the call at left guard. I thought that Bowie played reasonably well last week in his first start at that position, but I'm guessing Seattle wanted to go with the experience/power factor that Carpenter brings against Justin Smith. Carpenter has played well against San Francisco over the past couple of games, so it makes some sense.
49ers inactives: CB Eric Wright, TE Derek Carrier, LB Nick Moody, OG Ryan Seymour, DT Quinton Dial, OG Joe Looney and WR Jon Baldwin
