Polak had grown dissatisfied with his lack of first team action at Twente, which prompted him to sign a pre-contract for next term with ADO Den Haag.
The 28-year-old defender has not seen eye-to-eye with coach Rene Vandereycken for some time, and it would appear the tension increased over the weekend as Polak was told his services would no longer be required.
It would appear Polak will see out the season with the club's reserves before moving to ADO in the summer.
