Career
Robert Rosén started his professional career in 2003 with the Division 2 team Alvesta Saskatchewan, and played there for two seasons. Rosén then went to Växjö Lakers of the HockeyAllsvenskan where he had great success, scoring a total of 176 points in 211 games. Rosén then signed with Modo Hockey to make his Elitserien debut in the 2010-2011 season.
His 2010-2011 season with Modo ended with 27 points in 65 games.
After that season, which ended in play in the Kvalserien qualification for the team in order to stay in Elitserien, Rosén signed with AIK of the same league. In May 2012, due to real-life issues, Rosén moved back to Växjö and signed a five-year contract with Växjö Lakers within the same league.
The contract will expire after the 2016-2017 season. Rosén"s move was very controversial among AIK fans, and as a result, his contract included a clause prohibiting him from playing the first two road games against AIK at Hovet in the 2012-2013 season.
The only road game against AIK in which Rosén appeared was played on February 26, 2013.
The game ended 4–1 in AIK"s favour.
