The Blues put captain Alex Pietrangelo on injured reserve on Tuesday morning, meaning he'll be out at least the rest of the week.

The team called up defenseman Jordan Schmaltz from San Antonio.

The team said that Pietrangelo has a lower-body injury. He was hit by a puck on Saturday in Detroit -- just minutes before Jaden Schwartz was hit, causing him to miss six weeks -- and while he briefly left the bench, he returned soon after and finished the game.
