Polish OH Anna Werblinska and Azeri MB Anna Kudakova-Nazerenko are registered as MKS Kalisz (polish second division) players.
I guess Werblińska won't be ready to play before playoffs but transfer window in polish leagues will be closed on Friday.
Maybe it's just 'friendly' agreement that if it's possible she will join for playoffs but not obligatory. She is close to Kalisz and probably wants to help the hometown club to advance if she is ready for this time.
