The Calgary Flames extended qualifying offers to 12 players including newly-acquired defenceman Dougie Hamilton.

The others to receive offers were: Lance Bouma, Drew Shore, David Wolf, Josh Jooris, Micheal Ferland, Bryce Van Brabant, Ken Agostino, Paul Byron, Max Reinhart, Bill Arnold and Turner Elson.

Hamilton was acquired from the Boston Bruins on Friday in exchange for a first-round draft pick and a pair of second-rounders. The Flames were one of many teams interested in the 22-year-old who is believed to be a possible candidate for an offer sheet from a rival team if he hits restricted free agency.

Calgary did not qualify Sena Acolatse, Ben Hanowski and John Ramage, making the trio eligible for unrestricted free agency on July 1.
