"I think he's moving well, he's progressing," Yeo said. "I think what we will say is just let's get him through a real good practice [Friday] and see how that goes.
"I think first thing's first. Let's have a good practice [Friday] and evaluate whether he's going to be a player or not."
Stastny's return would boost a Blues offense that has scored seven goals in the series. They lost 2-0 in Game 4.
"I just think it's a tight series," Stastny said. "I feel like I've played [the Wild] a few times in my career and playoffs, and no matter what team they have, they have a bunch of two-way hockey players and it's a tight series. Sometimes you just need special teams to kind of get things going. Yesterday was 2-0, but every game's been 1-0, 2-0 or 2-1. You've just got to keep digging at it and keep battling."
The Blues are averaging 1.75 goals per game, a number that drops to 1.50 without the empty-net goal they scored in Game 3.
"First off, [the Wild] are defending very well, we're defending very well," Yeo said. "It's tight checking. It's good hockey right now. Certainly looking back and watching the video especially, not nearly enough net presence at their net right now. We're drifting away from their net so we have to do a better job of that. You look at [Wednesday], and again, we weren't good enough but we had probably four opportunities to shoot pucks that could be scoring chances or could lead to secondary opportunities and we're passing up those shots. So we have to do a better job of that as well."
