Here are some player updates:

- Forward Yan Stastny is expected to miss about four weeks with a broken thumb. Stastny was hit in the thumb on a shot by defenseman Roman Polak Sunday against Edmonton. Stastny stayed in the game and wound up scoring the team’s only goal.

- With Stastny out of the lineup, it appears that forward Alex Steen will take his spot. Steen (foot) did not participate in the morning skate, but he is expected to play. Steen took a shot off a foot Friday in Vancouver, but a X-ray Sunday showed no break.

- Defenseman Jay McKee will be back in the lineup tonight, after missing the last 11 games with a fractured ring finger. Right now it looks like Mike Weaver (upper-body injury) will not play.

Blues coach Andy Murray has reunited the line of Oshie, Berglund and Perron. He met with each of those three individually and as a line this morning.

“That unit should play hard every night,” Murray said. “They’re kids . . . they may make mistakes, but they need to play hard every night and they haven’t been. We’re hoping that Oshie can add to that a little bit. We were a little hesitant (to make the change) because we felt Backes and Oshie had something going. But they’re looking forward to playing together.”

Oshie, Berglund and Perron were playing together before Oshie’s ankle injury. Now that Oshie is back, they hope to stay together

“I think if you’re going to be a good line, I think you have to play with them for a while,” Berglund said. “It’s hard to get used to everything in one or two or three games. If you’re really going to trust each other, believe each other and find each other, I think you have to play with each other for a long time. If we don’t score in two or three games, we can still find each other. It doesn’t happen overnight. So I think we need some time and it will be really good. But first, we have to be the line that skates all the time and gives a lot of energy to the team . . . after that, the scoring chances are going to pop up.”
