The 24-year-old was selected in the first round (No. 24) of the 2007 NHL Draft by the Flames and reached career highs of 10 goals and 25 points during the 2010-11 season.
Last season, Backlund had eight goals and 16 points in 32 games.
“Mikael really stepped up last season and took advantage of the change in direction under a new coaching staff,” Flames general manager Jay Feaster said. “He came into camp in very good shape and also had regained his confidence. He parlayed that into a strong season, and if it wasn’t for his (foot) injury we believe he would have progressed even further in his development. We need Mikael to be one of our go-to players this year, and we are excited about watching him continue to evolve and take that step to the next level as a player.”
