Schwartz last played on Feb. 12 in Arizona and has been out of the lineup for 15 games with a lower-body injury.
"It's going to be awesome to have him back," Zach Sanford said of Schwartz. "I think everybody knows how dynamic he is, offensively making plays and creating opportunities for our team. The last couple years, as long as I've been here, he's been one of the top players at creating those chances and coming up with big plays when we need them... That's something we need right now. "
Schwartz has played in 14 games for the Blues this season, posting two goals and seven assists (nine points) and a plus-9 rating.
