Wallstedt was summoned from AHL Iowa on Saturday, per Michael Russo of The Athletic.
EDGE Analysis
Marc-Andre Fleury suffered an upper-body injury versus Florida on Friday, so Wallstedt could back up Filip Gustavsson on Sunday against Carolina. Wallstedt made his NHL debut Jan. 10, and it was a tough one, as he gave up seven goals on 34 shots in a loss to the Stars. He is a highly-regarded prospect and is worth claiming in dynasty leagues.
