The Hurricanes had sent Murphy to Charlotte on Monday.
Murphy, Carolina's first-round pick (No. 12) in the 2011 NHL Draft, is expected to practice with the team on Wednesday. The Hurricanes open their regular season Friday night at home against the Detroit Red Wings.
Murphy is entering his first full professional season after four years with the Kitchener Rangers of the Ontario Hockey League. He was scoreless in four games with Carolina last season.
I have been blessed to play for 16 years in the NHL; it has been an amazing ride. I would like to thank the Tampa Bay Lightning and New York Rangers organizations and owners for providing me the opportunity to play the sport I love for so many years. I could have never played for so long or accomplished all that I have without the unwavering love and support from my wife, Heather, our three sons, Ryan, Lucas, and Mason, and my parents.
