[2] According to the competition rules, all clubs are required to field at least one youth player (born on 1993 or later and Polish or trained in Poland) in every game (except for the times when the only youth player on the roster is sent off or unable to continue playing).

A day later, Energetyk ROW and Chojniczanka joined them as champions and runners-up of II liga West following Bytovia's 4–0 loss to MKS Kluczbork.

On 28 May 2013 the PZPN announced their final decision that highly indebted Polonia Warsaw will be demoted from Ekstraklasa.

However, the club again failed to meet the Polish FA's financial criteria and will play in the North Mazovia IV liga.

As a result, the 15th placed teams of the 2012–13 Ekstraklasa (Ruch Chorzów) and the 2012–13 I liga (Okocimski KS Brzesko) avoided relegation.
