Stone, 26, signed a one-year, $4 million contract with the Coyotes on July 28, according to capfriendly.com. He can become an unrestricted free agent after this season.
"Calgary's pushing for a playoff spot and they are hoping Michael Stone can give them a jolt, which I think he can," Coyotes general manager John Chayka said. "From my perspective, we have some good young defensemen here, and [the trade] gives them an opportunity to play more."
Stone had an NHL career-high 36 points (six goals, 30 assists) in 75 games last season before he tore the ACL and MCL in his left knee in a collision near the boards with Michael Raffl of the Philadelphia Flyers on March 26, 2016. He had reconstructive surgery in April, and has a goal and eight assists in 45 games this season.
The Coyotes selected Stone in the third round (No. 69) of the 2008 NHL Draft, when Calgary GM Brad Treliving was an assistant GM with Arizona.
"He's a right-shot defenseman, which are hard to come by, and he can do a lot of things," Treliving said. "He can play on both sides of special teams.
"Mike's probably going through one of his toughest years. He came back from a real serious knee injury. Those things are hard to come back from. When we looked at our team, one of the things we tried to do was to see if we could add depth to our blue line."
Stone has 24 goals and 72 assists in 324 NHL regular-season games in six seasons, all with the Coyotes.
