QB update

This much we know: backup Brooks Bollinger isn't practicing today. He came out to practice in a baseball cap, alongside Brad Johnson.
Also, the Vikings added Drew Henson to the practice squad again, another indication Bollinger probably won't be able to play this weekend.
Signing Henson means they want to have an extra body to take snaps during practice this week.
Meanwhile, Vikings coach Brad Childress was coy about who would start. He said a decision had been made. But he declined to say who would start. Around the same time, rookie Tarvaris Jackson indicated things were status quo, although he hedged shortly thereafter.
We'll keep you updated.
