Morrow was not on the ice for Friday's training camp session, Cory Lavalette of the North State Journal reports.
Morrow made his NHL debut last year, registering six shots, one hit and a minus-3 rating in two outings. Barring a long-term injury, the youngster should be in the mix for an Opening Night roster spot, though all three pairings seem fairly set heading into the start of preseason action. Don't be surprised to see Morrow starting the year with AHL Chicago but being atop the shortlist of potential call-ups.
