According to an early Associated Press account, Favre told Leno he doesn't know if he will play in 2010 and doesn't plan an announcement anytime soon. The interview was taped earlier Thursday and will broadcast late Thursday night.
I'll bring more updates as necessary, but I don't think any of us really thought we would get much in the way of news out of this. I still believe Favre will play for Minnesota this season, as much as one can reasonably speculate about his future. It's just a matter of when he shows up.
