Popović was a member of the Serbia and Montenegro youth teams.
Popović started his professional career in FK Čukarički Stankom and played for the club between 2000 and 2009, he also made a small appearance in Ligue 2 with Stade Brestois 29 in the 2005/2006 season.
In March 2009 he made a move to South Korea and Daegu FC. However, he was released in June 2009 from the club after failing to score goals. In August the same year Popović signed a contract with the Bosnian side FK Željezničar Sarajevo. In May 2010 he won the Premijer Liga with Željezničar and was also a runner-up in the Cup of Bosnia and Herzegovina.
In December 2011, he signed with Malaysia Super League side Perak FA. Earlier reports from Malaysian media quoted Perak management have released Popović from his contract on 1 April 2012, however later reports stated that Perak management have retained his services until 16 April, the last day for registration window for import players. On 14 April 2012 he managed to score his only goal for Perak in his final game with the team, in a 3-1 win against Sabah FA. He ended his stint with Perak with only one goal in 16 appearances in all competitions (14 league matches and 2 cup matches).
After his release from Perak, he returned to Europe to join Albanian Superliga team FK Kukësi for the 2012-2013 season. At Kukësi, Popović enjoyed some renaissance to his career, becoming his club top scorer in 2012-13 with 20 goals, including 16 goals in the league to make him second top scorer in the league and helping his club to 2nd position overall that season.
