His father, Kim Clackson, played in the National Hockey League (National Hockey League) for the Pittsburgh Penguins and Quebec Nordiques.
Clackson attended Peters Township High School in McMurray, Pennsylvania, and played for the school"s varsity ice hockey team, winning two Pennsylvania State Associate of Arts Ice Hockey Championships.
He was a teammate of NHLer Christian Hanson at Peters Township. After high school, he played two seasons of Junior A with the Chicago Steel of the United States Hockey League (USHL) and was selected 215th overall in the 2005 National Hockey League Entry Draft by the Philadelphia Flyers. Following his draft, he spent three seasons with Western Michigan University of the National Collegiate Athletic Association circuit.
After his junior season, he decided to forgo his senior year by signing with the Flyers on March 19, 2008.
That same day, he was assigned to the Philadelphia Phantoms of the American Hockey League (AHL). He played two games with the AHL team to close out the 2008-2009 season.
Clackson then played three full seasons with the Philadelphia/Adirondack Phantoms, re-signing with the Flyers following the 2009-2010 season. On June 7, 2011, Clackson was packaged into a trade that sent him, a 2012 third round draft pick and future considerations, to the Phoenix Coyotes, in exchange for goaltender Ilya Bryzgalov.
Failing to come to terms with the Coyotes on a new contract, he became an unrestricted free agent on July 1.
Several months later, he was invited to the Vancouver Canucks on a tryout basis during the team"s training camp. On July 14 2012, Clackson signed a one-year deal with the Washington Capitals. He will earn $525,000 at the National Hockey League level and $75,000 at the AHL level
On April 2 2013, he was traded from Washington to the Phoenix Coyotes in return of Joel Rechlicz.
During the 2011-2012 pre-season, Clackson was illegally hit from behind by Calgary Flames forward Pierre-Luc Letourneau-Leblond. In handing down a five-game suspension against Letourneau-Leblond, Brendan Shanahan, the new head of National Hockey League discipline, posted on the National Hockey League website video of the hit on Clackson to illustrate his ruling - the first of what would become Shanahan"s trademark video explanations.
