The Calgary Flames have signed veteran defenseman Nicklas Grossmann to a professional tryout offer, reports Sportsnet's Roger Millions.

Standing 6-foot-4 and 230 pounds, Grossmann could add more size to Calgary's blue line. The 31-year-old also has 589 games of NHL experience, scoring 86 points over that time.

He spent last season with the Arizona Coyotes after previous stops in Philadelphia and Dallas.
