Quinlan will remain on the Rush bench for the 2014 NLL season as an assistant coach in charge of the club's defence. The Sherwood Park, Alta., native will replace Devan Wray, who leaves the team due to family commitments.
"Deciding to walk away from the game of lacrosse was not an easy choice, but the opportunity to move into a coaching role is something I have always wanted to do which makes the decision easier." Quinlan said in a statement.
Quinlan joined the Rush for its inaugural season after one year with the Toronto Rock. He went on to become Edmonton's captain for his final two years with the team.
He finishes as the second-leading scorer in team history with 219 points.
Quinlan's lone goal in the 2013 campaign allowed him to reach the 100-career goal plateau. He also finishes with 119 assists with the Rush, and ends his nine-year career with 229 regular-season points, 544 loose balls, eight points in seven playoff games and two NLL all-star game appearances.
