All three Vikings quarterbacks were active Thursday night against the Washington Redskins, adding more intrigue to a saga that has no ending.

Matt Cassel knew he was backing up Christian Ponder so he was most prepared to step in when Minnesota's starter dislocated his shoulder late in the third quarter of the Vikings' 34-27 victory at the Metrodome.

Josh Freeman, however, remains a $2 million enigma following his ugly, unprepared performance Oct. 21 against the New York Giants, two weeks after the Vikings signed him following his acrimonious release from Tampa Bay.

"I'm making a lot of progress from my first game," Freeman said in the locker room. "I can't speak for the coaches. I can't speak for (head coach) Leslie (Frazier). I'm just working as hard as I can. When they need me to go in I plan to go in and play well, whenever that may be."

With seven games remaining, and Ponder now injured, Cassel appears poised to seize the reins again. He threw a pair of touchdown passes to deliver a Week 4 victory over the Pittsburgh Steelers in London after Ponder suffered a rib injury following Minnesota's 0-3 start.
