He won the bronze medal at the 2005 FIBA Europe Under-20 Championship, as a member of the Serbia and Montenegro junior national team. His breakthrough in the senior Serbian national team was set back by injuries, but he was eventually a part of the preliminary Serbia national squad during training camp for the 2014 FIBA Basketball World Cup. The then 29-year-old was widely expected to make the team's final roster cut, however, during the last preparation friendly game, against New Zealand, Micov got into a mid-game argument with Serbian head coachAleksandar Đorđević, that led to Đorđević taking Micov out of the game, and later expelling him from the bench. At the post-game press conference, the Serbian coach announced that, "Micov's short career in the national squad has ended", with Micov later saying to the media that he read the coach's words, and that he accepted his decision, while also stating that Đorđević was, "maybe too nervous".
