Polonia Warszawa and Eryk Mikołajewski have mutually agreed to terminate his contract. The club had previously placed him on the transfer list and aimed for a separation to occur soon. Despite efforts, Mikołajewski was unable to find a new employer in the market. He previously spent the spring round of last season on loan at Mławianka Mława and was recently moved to Polonia's reserves.

Eryk Mikołajewski is on the transfer list published by Polonia Warszawa, who are looking to make room in their squad for new signings.
