Willis inactive for 49ers

Despite saying this week that he intended to play today, 49ers’ linebacker Patrick Willis is inactive today.

There are no surprises among the Seahawks’ inactive players:

CB Kennard Cox

LB Malcolm Smith

QB Josh Portis

SS Jeron Johnson

OG Paul Fanaika

DT Clinton McDonald

OT Jarriel King

McDonald practiced on a limited basis on Thursday, but sat out Friday’s walk-through because of his concussion. His absence in the rotation could hurt the Seahawks in their quest to contain 49ers running back Frank Gore.

Also inactive for the 49ers:

QB Scott Tolzien

WR/KR Ted Ginn

CB Tramaine Brock

OG Daniel Kilgore

OG Mike Person

NT Ian Williams
