With Morin gone, the Hawks have 13 forwards and nine defenseman, including rookie Nick Leddy, remaining on their roster with two days left to prepare for their season opener Thursday night against the Avalanche in Colorado.
Morin was one of the most impressive players in training camp and in exhibition play, outplaying other prospects such as Kyle Beach and Igor Makarov and putting pressure on older players considered favorites to make the Hawks.
"It was a good experience, my first time with the Blackhawks here," Morin said after the Hawks' final preseason game Sunday against the St. Louis Blues. "I think it went well. I had a pretty good preseason."
