In October 2005, Tselios signed with KalPa of the Finnish SM-liiga and played with them until January 31, 2006, when he moved to Färjestads BK of the Swedish Elitserien. He scored his first goal at Färjestad on March 25 in the semifinal of the Swedish Championship against HV 71. He then played in the United Hockey League with the Chicago Hounds before returning to Sweden, signing with HK Örebro in the Swedish First Division, the country's third-tier level.[4]
