"He's feeling good. It's a real good sign that he's out there with us," Blues Head Coach Craig Berube said Thursday. "He'll skate with us (Friday) and we'll go from there."
Perron has missed five games so far with an upper-body injury.
In 20 games this season, Perron has posted seven goals and 11 assists (18 points).
"It's nice to see him out there smiling, joking around and being the guy he is," added Blues forward Brayden Schenn. "He's one day closer to playing, and whenever that day comes, we're obviously looking forward to him being back in the lineup."
