Eriksson started at the Junior World Championships 2002 in Schonach for the first time in an international ski jumping competition. In the same year he took part in the first competitions of the Continental Cup (COC). After the 2003 Junior World Championship in Sollefteå , where he finished 15th, he started regularly in COC jumping. After he was able to perform consistently there and achieved a 20th place in the overall ranking of the Summer Continental Cup in 2003, he started in the World Cup from the 2003/04 season . There he initially struggled to reach the second round, but improved in the second half of the season and was able to occupy a 38th place in the end. He achieved his first World Cup points when jumping in Liberec, Czech Republic on January 11, 2004, when he achieved 16th place. A result that he would no longer achieve in his further career. He also took part in the 2004 Ski Flying World Championships , which took place in Planica in February . He was able to set a new Swedish distance record with 202 m. He is the first Swede to jump the 200-meter mark. After the season he had to train alone for a while without a trainer due to the miserable financial situation of the jumping division of the Swedish Ski Association. Nevertheless, he was able to jump into the top twenty in two competitions at the Summer Grand Prix . During the 2004/05 World Cup, however, he was completely out of shape and could not reach the points in a single competition. Even when in Oberstdorf held FIS Nordic World Ski Championships 2005 , he had no chance and was from the normal hill he failed on the large hill, only 48 did in the qualifiers. After Eriksson started to build up again in the Continental Cup in summer 2005, he fell ill with glandular fever , which set him back in his development. Therefore he entered the World Cup 2005/06 only at the end of January 2006, but could not achieve good results. After having competed in the COC again and even in two FIS Cups in the summer of 2006 , he commuted back and forth between the World Cup and the Continental Cup in winter 2006/07. While he was unsuccessful in the World Cup, in February 2007 he was able to achieve a second place in two Continental Cup competitions in Pragelato, Italy and Westby in America . In the summer of 2007, however, he could no longer build on these achievements and always missed the final in the Continental Cup. In the winter of 2007/08 he commuted between the World Cup and the Continental Cup again. A 25th place at the COC in Garmisch-Partenkirchen was his best result. At the Ski Flying World Championships 2008 in Oberstdorf, in which he also took part, he did not survive the qualification in the individual competition. In the team competition, the Swedish team, which Eriksson also belonged to, was able to achieve eleventh place , leaving behind the more prominent teams from Slovenia and Kazakhstan . In the summer of 2008 he was able to achieve a sixth place in the final competition of the summer COC in Falun . In 2009 he ended his career.
