Maroš Kolpak had lost his contract with German handball club TSV Ostringen, as his team already had two non-EU players.
In March 2004, South African cricketer Claude Henderson became the first player to sign a Kolpak agreement, which ended his international career.
However, the British Home Office stipulates that a player must have a valid work permit for four years or must have a specified number of appearances in international cricket to sign a Kolpak deal.
This is aimed at reducing the mass arrivals of overseas players into county cricket.
