The Flames put the 45-year-old on waivers Sunday, two weeks after he was placed on injured reserve with a lower-body injury, retroactive to Dec. 31. Jagr hasn't played in a game since New Year's Eve.
"Jaromir's career speaks for itself," Flames general manager Brad Treliving said in a release. "He is a legend in our sport and we are very appreciative that he selected Calgary to pursue his career in the NHL. Regretfully, with a late start to his season combined with nagging injuries, he wasn't in a position to perform at the level both he and our team had hoped.
"During his short time in Calgary, Jaromir demonstrated tremendous leadership and professionalism, especially with our young players. We thank him for his contributions to our group both on and off the ice."
Jagr tallied a goal and six assists in 22 games after signing with the Flames on a one-year, $1 million deal in October.
"Although I am very disappointed that things did not turn out as we had hoped due to a number of circumstances, I am deeply grateful to the Flames, the fans and the City of Calgary for having welcomed me so generously," Jagr said in the release. "I now look forward to continuing the season in Kladno."
A native of Kladno, Jagr owns the team he will play for, which is in the Czech second division.
In 24 NHL seasons, Jagr ranks third in NHL history in games played (1,733) and goals (766), and second in points (1,921). He also spent five seasons in the Kontinental Hockey League (2004-05, 2008-11).
