The combination of Christian Abbiati's return from his loan spell at Atlético Madrid and a poor performance in Milan's 5–0 Russian Railways Cup thrashing at the hands of Chelsea F.C. on 4 August 2008 spelled the end of Kalac's brief first-team run. He was consequently demoted to third-choice behind Abbiati and Dida, and did not play for Milan again until appearing in the second half of a friendly against Hannover 96 on 29 January 2009, and one Serie A appearance against Juventus as an injury replacement on 10 May. He was released by Milan on 11 August, following an agreement reached with the club.
