Morrow was assigned to AHL Chicago on Sunday.
Morrow was sidelined for several weeks early in training camp due to an undisclosed injury. While he's now recovered, the 21-year-old will begin the regular season in the minors. He made 37 appearances for UMass-Amherst last year, tallying six goals and 30 points. Morrow could rejoin the Hurricanes at some point if the team deals with injuries.
