Chiasson spent the last two seasons with Ottawa after being acquired as part of the Jason Spezza trade in 2014. Last year, he played in 77 games with the Sens, recording a career low 8 goals and 6 assists. In 239 career NHL games, the 25 year old has 38 goals and 44 assists.
Sieloff was Calgary’s 2nd round pick (42nd overall) in 2012. He made his NHL debut this past season, scoring in his lone game. He also suited up in 52 games with their AHL affiliate in Stockton, picking up 2 goals and 9 assists.
Shortly after the deal was announced, the Flames announced that they have inked Chiasson to a one year contract. Sportsnet’s Chris Johnston reports the deal is for $800,000, well below his qualifying offer of $1.2MM.
