Ferland gets a four-year deal with an average annual value of $3.5 million, according to reports.
Ferland provided a grittiness the Canes needed, finishing third on the team with 182 hits. He also added some offense to go with his physical play with 17 goals and 23 assists.
The 26-year-old only had one assist in seven playoff games, but he missed considerable time after sustaining an injury on a hit of Capitals big man Tom Wilson in the first round.
Ferland is coming off a two-year, $3.5 million deal that he signed with Calgary.
