First League 2008–09 champions Widzew Łódź were not permitted to advance by the Polish FA after their involvement in the Polish corruption scandal. The club had its initial appeals rejected, however, an Arbitration Tribunal later returned a verdict in the club's favor which led the club to file a request for immediate reinstatement to the Ekstraklasa.
The decisions had a significant influence on the relegation and promotion of teams. As a consequence of their revoked license, ŁKS were put in last place of the 2008–09 Ekstraklasa standings and directly relegated to the First League. They were joined by Górnik Zabrze as 15th-placed team. Both teams were replaced with First League 2008–09 runners-up Zagłębie Lubin and third-placed Korona Kielce.
Because of the controversy surrounding both teams from Łódź, the Polish FA was forced to postpone the originally planned relegation/promotion play-off in June 2009 and eventually decided to cancel it completely.
