With lack of on-field successes and failure to climb the league pyramid, the club withdrew half through the Fourth Division in the 2002–2003 season, officially disbanding in March 2003. The club reformed under the name "KKS Prosna Kalisz" but failed to field a senior team. The fans and management of the club decided to re-establish the club from scratch in 2006, starting from the bottom of the football pyramid, the 8th division, and earned promotion in their first season. In that decision, they also decided to establish a women's football team.
