Career
Laursen was predominantly used in the central defense, but was also competent as a left back. He began his career at Odense Boldklub, where his talent was quickly discovered. He transferred to Hibernian under manager Alex McLeish, on a free transfer in 2000.
He was a fans favourite at Easter Road, scoring five goals in 82 appearances and helped the club reach the 2001 Scottish Cup Final against Celtic, which they lost 3–0.
He signed for Celtic in a £1.3 million deal in August 2002, and his first season saw him enjoy an extended run in the first team, thanks to injuries to other players. However, he failed to make any appearances the following season aside from one substitute appearance in the League Cup.
He saw more playing time during the 2004-2005 season, but he moved back to OB in the summer of 2005. Laursen then transferred to F.C. Copenhagen in January 2008.
After only six months in Copenhagen, Laursen was selected as new captain after Michael Gravgaard"s departure to Football Club Nantes.
On 11 May 2010 Laursen confirmed that he will retire at the end of the 2009-2010 season.
