The Hurricanes have been without a captain since trading Eric Staal, Jordan's brother, to the New York Rangers in February 2016. Jordan Staal and Faulk joined forwards Jeff Skinner and Victor Rask as alternate captains last season, with Skinner remaining in that role for the 2017-18 campaign.
Coach Bill Peters announced that Jordan Staal would serve as the team's captain at home, while Faulk would have the honor on the road. The players will switch at midseason, Peters said.
