Veikkausliiga side IFK Mariehamn, for example, decided not to register for the tournament, as well as some Ykkönen teams.
These four teams entered in Round 6 because they qualified for European competitions after the 2008 season.
The tournament started on 28 March 2009 with the First Round and concluded with the Final on 31 October 2009 at Finnair Stadium, Helsinki.
Inter Turku defeated Tampere United 2–1, giving them a place in the second qualifying round of the 2010–11 UEFA Europa League.
They have since been promoted to the third qualifying round because Atlético Madrid, winners of the 2009–10 UEFA Europa League, are now assured of qualifying domestically for the 2010–11 Europa League, either as winners of the 2009–10 Copa del Rey or losing finalists to a Champions League-qualified Sevilla.
This round included the 28 winners from the previous round and the 4 Veikkausliiga 2009 clubs involved in European competition in the 2009-10 cycle: Inter Turku, FC Honka, FC Lahti and HJK Helsinki.
These matches were played on 8 and 9 July 2009 except for the match between FC Viikingit and FC Lahti, which took place on August 12 due to Lahti's involvement in the Europa League.
