The 23-year-old Boychuk was the 14th pick in the 2008 NHL Draft, but was never able to find a regular place in the Carolina lineup. He played in the Hurricanes' season opener and hadn't seen action again since.
In 73 games over parts of five seasons, Boychuk posted seven goals, 18 points and a minus-4 rating. He was a 20-goal scorer each of the past two seasons for Carolina's American Hockey League affiliate, the Charlotte Checkers.
"He's a guy who's a first-round pick," Bylsma said. "He's got speed to his game. He's got limited NHL experience, but he's going to add some competition in our lineup. He could see time on Malkin's line on that wing and see him in that position and adding speed and a little bit of grit to that line."
