Former Australian Test forward Dallas Johnson has been released from his Melbourne Storm contract to join the Catalans Dragons in the European Super League, the club said on Thursday. Backrower Johnson, who played one Test for the Kangaroos in 2007 and 12 State of Origin matches for Queensland, sought an early release from his club contract to take up a three-year deal with the French club, Storm said. Johnson, 26, won the NRL premiership with Melbourne in 2007 and again this year. 'This was without doubt the toughest decision of my career,' Johnson said on Thursday. 'There are other areas of life I want to explore and living abroad and travelling is absolutely up there on the list. 'The opportunity to continue my rugby league career with the security of a long- term deal and in such a beautiful part of the world was one that I couldnt refuse.'
