Stone was put on waivers by the Flames on Thursday in order to buy out his contract, Elliotte Friedman of Sportsnet reports.
EDGE Analysis
With the buyout, Calgary will save $2.3 million against the cap this year, which will help it sign restricted free agent Matthew Tkachuk. Considering the 28-year-old Stone was only able to break into the Flames' lineup on 14 occasions last season, he could struggle to secure an NHL deal, though a training camp professional tryout agreement could be in his future.
