Matinpalo (upper body) won't play against St. Louis on Tuesday, and there is no timeline for his return, Bruce Garrioch of Postmedia reports.
Matinpalo suffered an upper-body injury in Monday's 4-1 win over New Jersey. He hasn't earned a point in six appearances this season, but he has posted four shots on net, eight blocked shots and four hits. Jorian Donovan will replace Matinpalo in Tuesday's lineup against the Blues.
