The Vikings have officially listed Brett Favre as doubtful for Sunday night's game against the Eagles. Favre is dealing with a concussion, but Minnesota is leaving the door open for him to play. The team listed him as "out" a week ago, but upgraded him to questionable the day of the game and he ended up starting against the Bears. "No 'out' with Brett Favre," Leslie Frazier said. "Will not use that term."
