As it became apparent that the following NHL season would be suspended due to a lockout, Samuelsson initially signed with Genève-Servette HC of the Swiss National League A in September 2004. He appeared in 12 games for the club, recording six points. A month after signing in Switzerland, he returned to Södertälje SK of the Elitserien in late October. He recorded 20 points over 29 games as the club qualified for the eighth and final playoff spot, where they were defeated by Färjestad BK in four-straight games. Samuelsson notched six points in ten post-season games.
