MINNEAPOLIS -- The Minnesota Vikings' unsettled quarterback situation took a new twist Wednesday as the team signed veteran free agent Patrick Ramsey.

Ramsey, joining his eighth team, has not played in a game since 2008 or started one since 2005. It's unlikely that he will start Monday night against the Chicago Bears, according to coach Leslie Frazier.

The starter probably will be rookie Joe Webb, who has served as the No. 3 quarterback all season until Monday and even played wide receiver two weeks ago. Last week's starter, Tarvaris Jackson, won't be able to play because of a turf toe injury, Frazier indicated.

In his weekly appearance on KFAN radio, Frazier said he remains hopeful that Brett Favre's shoulder injury will heal enough for him to play. However, Favre didn't sound overly optimistic after missing Monday's game against the New York Giants.

That leaves Webb, who has been bothered by a hamstring injury, or Ramsey to start against the Bears in Monday's game expected to be played at TCF Bank Stadium.

"Joe Webb has the most familiarity with our offense," Frazier told KFAN. "He's been with us the entire season. Although he's coming off a hamstring injury, he'd be the next candidate. The next guy (Ramsey) would have to be ready to go in if something were to happen with Joe."

Ramsey has bounced around in recent years. He's been with Miami and Jacksonville this season and spent time with Detroit and Tennessee last season. He previously played for Denver, the New York Jets and Washington in his eight-year career.
