On 25 September 2007, Karadžić became the president of Partizan Belgrade where he came following the decades-long reign of Nenad Bjeković, Žarko Zečević, and Ivan Ćurković at the club.
In March 2008, Terzić fled the country after getting indicted for embezzlement of player transfer funds and Karadžić took over his role as FA president.
During his university days in Belgrade, after beating up a fellow student in the faculty commissary and causing him injuries that reportedly led to the victim losing an eye, twenty-two-year-old Karadžić was charged with aggravated assault in 1961 and sentenced to a year-and-a-half prison term.

His adversary Zvezdan Terzic — a football administrator who also drew strong criticism by Serbian public for of similar reasons — called for the convening of a special meeting of the Federation Parliament and the immediate withdrawal.
