The Calgary Flames bought out the final season of defenseman Michael Stone’s contract.
He is now an unrestricted free agent.
Stone, 29, signed a three-year, $10.5 million deal with the Flames in June 2017 after being acquired earlier that year in a trade with the Arizona Coyotes.
In his two-plus seasons in Calgary, Stone had 21 points (five goals, 16 assists). In 2018-19, he had five assists in just 14 games, missing a big chunk of the season with a blood clot.
A third-round draft pick by Arizona in the 2008 draft, Stone has appeared in 439 regular-season games and has 117 points (29 goals, 88 assists). He added one goal in six Stanley Cup Playoffs games.
