49ers v. Rams live blog: Pregame

SAN FRANCISCO — This is the live blog for the pregame of the 49ers’ Week 13 game against the Rams. I’ll update this frequently with information and analysis from the press box.

11:37 Michael Crabtree will start instead of Mario Manningham.

11:38 The 49ers inactives are Quinton Patton, Tarell Brown, Quinton Dial, Mike Iupati, Jon Baldwin, Garrett Celek and Tank Carradine.

11:39 The Rams inactives are Daryl Richardson, Daren Bates, Harvey Dahl, Barrett Jones, Mike Person, Jermelle Cudjo and Gerald Rivers.

12:02 It will be interesting to see how Jeff Fisher tries to stop the 49ers’ offense. I imagine he will put 8 defenders in the box, jam Boldin on third down and try to make Kaepernick go through his progressions to win.

12:32 Crabtree is the split end in warmups. Boldin is the flanker.
