Rust was reassigned to AHL Wilkes-Barre/Scranton on Tuesday, Seth Rorabaugh of the Pittsburgh Post-Gazette reports. Rust was brought up from the minors a day earlier due to the uncertainty of Patrick Hornqvist's (lower body) availability for Tuesday's game. However, after Hornqvist was able to participate fully during the Pens' morning skate, he was subsequently activated from IR, resulting in Rust's demotion to the AHL. The 22-year-old has two points over his 14 games with the Penguins this season.
