After earlier being listed as out for Monday night's game against the Bears, Vikings QB Brett Favre now has been upgraded to questionable.

Rookie Joe Webb is still expected to start, but Favre would take his place if he's healthy. Favre's streak of 297 consecutive games came to an end last week in a loss to the Giants, a game that was moved to Detroit's Ford Field because of severe damage to the roof of the Metrodome.

Monday night's game also has been moved, this time to University of Minnesota's TCF Bank Stadium, which will make it the first outdoor NFL game in Minnesota since 1981.

The field conditions have been a subject of a lot of conjecture, as freezing temperatures and expected snowfall could make the surface very icy. Volunteers helped shovel snow all week to prepare the field for the game. However, there is no heating coil below the surface of the field, as there are in NFL cold-weather stadiums such as Soldier Field and Lambeau Field.

It's not known if the potential field conditions were a consideration in downgrading Favre to out originally.

Webb would be making his first start, and the team signed Patrick Ramsey to serve as his backup. The only way Favre could play before the fourth quarter, other than if the other two QBs are injured, is if he's listed as one of the top two QBs.
