CHICAGO -- It's a beautiful day along Lake Michigan, but don't be fooled by how placid Soldier Field probably appears on TV.
The flags on the goalpost are pretty flat, but trust me, there's a pretty good breeze at field level. I know that's usually the case here, but just something to keep in mind as this game progresses.
By the way, the Bears are wearing their orange jerseys Sunday. They've encouraged their fans to wear orange as well.
Meanwhile, one late roster move to bring you: The Vikings activated linebacker Rufus Alexander from the practice squad and waived linebacker Erin Henderson. Alexander is active for this game.
