Simon Després (born July 27, 1991) is a Canadian professional ice hockey defenceman who is currently playing with Kölner Haie of the Deutsche Eishockey Liga (DEL). He was drafted in the first round, 30th overall, in the 2009 NHL Entry Draft by the Pittsburgh Penguins and has also played for the Anaheim Ducks. During a game in 2015, he suffered a severe concussion that complicated his career due to recurring symptoms, forcing him to miss nearly all Ducks games to follow; out of concern for his condition, the Ducks bought him out. He later signed with HC Slovan Bratislava of the Kontinental Hockey League, before attempting to return to the NHL via the Montreal Canadiens who assigned him to the Rocket, their AHL affiliate.
