McGroarty was reassigned to AHL Wilkes-Barre/Scranton on Wednesday.
McGroarty's demotion shouldn't come as a surprise considering he didn't play versus Montreal on Monday and was set to be scratched again Wednesday. General manager Kyle Dubas told reporters at the start of the season that he didn't want the 20-year-old winger sitting in the press box, so this move appears designed to get him some minutes. The Baby Pens play Friday and Saturday in a home-and-home with Lehigh Valley, which could see McGraoarty remain in the minors through at least Pittsburgh's next two contests, though it could certainly be longer.
