In October 1993, Larsen turned professional winning his first fight in Storebaelthallen, Korsoer, Denmark on the undercard of a bill that included Danish stars Johnny Bredahl, Jimmy Bredahl and Brian Nielsen. In that fight Larsen beat England's Martin Jolley with a knockout in the fourth round.^[1]

Following a shoulder injury as well as a promotion dispute, Larsen spent over three years out of the ring and returned in May 2007 after he signed with Sauerland Promotions. Since his return, Larsen has won all his fights and had an EBU title fight scheduled for January 16, 2010 in Aarhus, Denmark. His opponent was originally planned to be Dimitri Sartison, who lost to Mikkel Kessler in a WBA title bout in June 2008.^[2]

Larsen made an unsuccessful comeback bid in January 2010, suffering a TKO to Brian Magee. After the fight, Larsen was accused of doping on the basis of a blood-sample, but was later cleared of all charges by the Danish Boxing Association ^[3]
