Vikings quarterback Brett Favre says he won't return to play next season. "I can promise you this: Not that I have ever set out as a goal to play 20 years, it's 20 years and I'm done. This is the last year of my contract," he said when the season began. Favre has a habit of changing his mind, so he was asked about his future again on Thursday night. "No," he said when asked if he would play in 2011.
