49ers @ Saints live blog: Pregame

NEW ORLEANS — This is the live blog for the pregame of the 49ers Week 12 game against the Saints in the Superdome. I’ll update this frequently with information and analysis from the press box.

11:01 I walked from my hotel to the Superdome. It took my dad and me about a half an hour. It seemed like the entire city was out tailgating. It was very festive and a lot of fun.

11:16 There are reports that Alex Smith has passed his final concussion test. If that is true, he will likely back up Colin Kaepernick today.

11:32 Kaepernick and Smith are both warming up on the field. Kaepernick is stretching his quads and Smith is running backward.

11:34 The Bears are slaughtering the Vikings 25-3 at halftime. I expected the Bears to struggle blocking Jared Allen. He has a sack and a QB hit, but he’s not affecting the outcome of the game.

11:36 The Raiders are losing 24-0 at halftime. Dennis Allen has made the Raiders worse somehow. I wouldn’t be surprised if he got fired after this season.

11:51 Kaepernick is throwing warmup passes to Ricardo Lockette. Smith is throwing to A.J. Jenkins, and Tolzien is throwing to Garrett Celek.

11:57 Brandon Jacobs is active. So is Alex Smith.

11:59 The 49ers inactives are Scott Tolzien, A.J. Jenkins, LaMichael James, Trenton Robinson, Will Tukuafu, Joe Looney and Ian Williams.

12:08 The 49ers announced “no lineup changes.” That’s ambiguous, because Alex Smith is listed as the starting QB on the depth chart, but the P.R. staff just said “Kaepernick is expected to start.”

12:12 The Saints inactive players are CB Corey White, CB Elbert Mack, LB Scott Shanle, T Zach Strief, T Charles Brown, DT Tyrunn Walker and DE Junior Galette.

12:24 Kaepernick and Smith are throwing warmup passes side by side. Jim Harbaugh is catching for Smith.

12:25 Smith just stopped throwing. He’s talking to Harbaugh. Smith seems to have a lot to say. Harbaugh walked away to talk to Vic Fangio.

12:26 Now Kaepernick and Smith are taking turns throwing passes to Harbaugh.

12:37 It is freezing in the Superdome. Mindi Bach is passing out Ricolas in the press box in anticipation of the cold that will hit all of us soon enough.

12:41 Kaepernick and Smith are taking turns throwing deep outs. It seems like Kaepernick’s passes get to the receiver twice as fast as Smith’s. Harbaugh is handing off to the running backs.

12:43 Smith just under threw Manningham by five yards on a deep post. Kaepernick over threw the pass immediately after.

12:46 Kaepernick is warming up with the first team offense against the first team defense. Smith is watching.

12:47 Now Smith is on the field warming up with the second team offense against the second team defense.

1:18 The Saints starting right tackle, Zach Strief, will not play. That means Ahmad Brooks should have a big game going against the Saints backup.
