In the 2005/06 season the two Allsvenskan leagues were combined into one league, the present HockeyAllsvenskan with sixteen teams. The first season only the four best teams were promoted to the Kvalserien directly, Nyköping came in on 11th place. From the 2006/07 season a play off was re-inaugurated, the top three teams are promoted to the Kvalserien directly, and the teams ranked 4 through 7 play each other in two play off rounds for the fourth spot. Nyköping came in on the 7th spot and beat the 4th team, VIK Västerås HK, in the first play off round, but lost in the next round to IF Björklöven.
