The 33-year-old MacIntyre has had two previous stints with the team. He broke into the NHL with the Oilers as an undrafted free agent in 2008-09. After splitting the following season with the Oilers and Florida Panthers, he returned to Edmonton in 2010-11 and played a career-high 34 games.
MacIntyre spent the past two seasons with the Penguins, playing a total of 13 NHL games while getting into 53 American Hockey League games with the Wilkes-Barre/Scranton Penguins.
In 91 career NHL games, MacIntyre has two goals, four points and 175 penalty minutes.
I definitely think going back down helped me, I had a lot of confidence down there, I played a lot of minutes and I think that helped me a lot. With the 37 games up here, that gave me experience as well. I know what it takes to play in the NHL and now it's time for me to show that I'm capable of being a full-time NHL player.
