Minnesota Vikings quarterback Christian Ponder dislocated his left shoulder during a win over the Washington Redskins.

He was replaced by Matt Cassel.

"My expectations are, I'm going to be back next week," Ponder told reporters. "We've got a great athletic training staff. They're going to do me right. I'm going to do everything I can to be back next Sunday."

The Vikings won the game behind Adrian Peterson's touchdown run.

Ponder completed 17 of 21 passes for 174 yards, two touchdowns and one interception.

"I think Christian's really growing," coach Leslie Frazier said. "He's more confident. He's showing more command. He's growing as a leader. Just the fact that he never got shaken, even after that interception. I'm sure he'll tell you, that was not the right decision to throw that football where he threw it. But that did not cause him to go in the tank and have self-doubt. He came back and played some of his best football. He's growing and maturing as a quarterback."
