In June 2006, Auld was involved in a multi-player trade that sent him, Todd Bertuzzi and Bryan Allen to Florida in exchange for Roberto Luongo, Lukáš Krajíček and a sixth-round draft pick. Initially, Auld was expected to be the undisputed starter in Florida. However, the July 25 signing of Ed Belfour introduced some competition, and Belfour eventually won the job as starting goalie. Controversially, in October, Auld was hospitalized while "horsing around" with Belfour, with suspicions that Belfour had assaulted him.
