RT @MaioccoCSN: 49ers inactives: Tolzien, Robinson, Hampton, Johnson, Jerod-Eddie, Looney, I.Williams.

Harbaugh brothers just had a quick meet-and-shake hands moment

Did Jim concur? RT @CamInman John grabs hand and pulls Jim in for a hug.

As you can see, the inactives for the game have already been announced. I'll have those posts, courtesy of the Baltimore Sun's Aaron Wilson, stick to the top of the blog until about game time.

Super Bowl inactives, which means we're only about 90 minutes from kickoff http://wp.me/p14QSB-79R4

Akers looks like he's hitting everything well in warm-ups. First clear miss was from 60, so no big deal. And then another off crossbar.

Someone in the press box just gave me the finger. Free PFT subscription to whoever guesses the culprit.

Ray Lewis: .... so I went to the sporting goods store and loaded up on Deer Antler spray.

Betting is a huge part of sporting events and there's nothing like it when it comes to the Super Bowl.

For Super Bowl XLVII, there are numerous proposition bets, also known as prop bets, that can spice up the betting climate with wagers that have little to do with the play on the field, draw upon historical games, and cross sport and pop culture barriers.

See the top 10 prop bets we found here.

Harbaugh brothers have chatted several times in last 30 minutes--each time the cameras come running and brothers get outta there.

RT @NFL_ATL: David Akers splits uprights from 57 in warmups. Haven't seen him miss yet.

Jim Harbaugh's playing with his daughters in the corner of the 49ers end zone right now. Just gave his wife and baby boy a big kiss.

Jim Harbaugh would not have been my first choice for Bring Your Daughter To Work Day

The Ravens fans are definitely louder than the 49ers fans.

RT @realfreemancbs: Ray Lewis on the field. Sources say Lewis has not cried.

Greg Bedard, the Globe's NFL writer, just posted to the Extra Points blog his intro for today's game. Here is that entry: NEW ORLEANS -- Welcome to the Superdome, where the 49ers and Ravens will square off in less than an hour.

Here are the inactives:

San Francisco - QB Scott Tolzien, S Trenton Robinson, RB Jewel Hampton, LB Cam Johnson, DT Tony Jerod-Eddie, OLJoe Looney, DT Ian Williams.

Baltimore - CB Asa Jackson, S Omar Brown, CB Chris Johnson, LB Adrian Hamilton, OL Ramon Harewood, WR Deonte Thompson, DT Bryan Hall.

I picked the 49ers to win by eight, 32-24, in the paper. More of my thoughts on the game and other NFL notes are in the Sunday Notes. Also penned a feature on Ravens safety Ed Reed.

A few of the key things to watch for in my mind:

Ravens TE Dennis Pitta vs. 49ers ILBs: The 49ers will understandably be holding their safeties back to keep Joe Flacco from hitting the deep ball. That should leave a lot of room in the middle for the field for the underrated Pitta (and receiver Anquan Boldin) to operate.

Ravens DEs Terrell Suggs and Paul Kruger vs. 49ers QB Colin Kaepernick: Expect the Ravens to be content to let Frank Gore some some a little damage inside; what they don't want to do is give up the edge to Kaepernick. That will lead to a blowout.

Ravens CBs vs. 49ers WR Michael Crabtree: The Ravens' cornerbacks are OK but they haven't seen many complete WRs like Crabtree. Kaepernick could play pitch and catch all day with Crabtree if he wanted to.

Jim Harbaugh wrinkles: I think Harbaugh is the best coach in the league and he's going to have a few wrinkles that are sure to catch the Ravens my surprise. Can't see the Ravens coming up with many surprises. They are who they are.

Ravens sending a message early: Expect the Ravens to have someone (safety Bernard Pollard?) to send a message, likely against Kaepernick, in the form of a vicious shot. They'll take the 15-yard penalty just to send a message that we're going to land the first punch and keep taking shots at you.

Ravens and 49ers warming up. Some loud rap music blaring through the speakers. Players seem to like it, especially swaggering Terrell Suggs
