Heavenor, a native of Victoria, British Columbia, cited wanting to spend more time with his family as a major reason for his decision. Another significant reason for his decision was that physicality that lacrosse brings was taking its toll on Heavenor's body.
Last season, Heavenor had two goals and two assists for Calgary in 16 games played. He also collected 55 loose balls and won 46 of 82 faceoffs.
Heavenor had been with the Roughnecks since 2007 and won a Champion's Cup with Calgary in 2009.
Heavenor began his National Lacrosse League career with the Minnesota Swarm in 2006, but was traded after the season to Calgary for the Roughnecks' second and third draft picks in the 2006 National Lacrosse League Entry Draft.
His advice to Calgary lacrosse fans is a simple one. According to the Calgary Roughnecks website, it is do not eat yellow snow.
