On 27 July 2005, Hearts announced that they had completed the signing of Bednář on a one-year loan deal from FBK Kaunas. He scored on his debut against Kilmarnock, and also in the 3–0 away victory over Dundee United. Bednář then cemented his place in Hearts folklore by scoring the only goal in the 1–0 victory over Rangers at Tynecastle. It was in this game, however, that he suffered a serious knee injury that ruled him out for most of the campaign. He made his return on 26 November against Motherwell in a 1–1 draw, and played his part in Hearts' successful second-place finish and Scottish Cup victory.
