Starting his career in Halmstads BK youth team, he was raised up to the senior team in 2003 and debuted against GIF Sundsvall in the premier game of the season, coming on as a substitute. Prior to the 2004 season, he had established himself as a player in the starting line-up and aided the club to become runner-up, two points behind Malmö FF. Djuric continued on as a starting player during the poor season of 2005, as Halmstads BK qualified for the 2005–06 UEFA Cup group stage, in which Djuric became the only goalscorer for the club, against Sampdoria. During the following seasons he started mainly as a midfielder but gradually stept up to become a forward.
