On 19 March 2011, CS Flacăra Faget signed Sergiu Popovici from youth club LPS Banatul where he spent 7 years, before moving to Vaslui on 25 January 2012. Club leaders expressed excitement about his signing. On 17 August 2012, Sergiu Popovici, along with Răzvan Neagu and Valter Heil, was loaned out to Voința Sibiu, but returned to Vaslui a few months later when the club folded. Popovici made his Liga I debut for Vaslui on 11 March 2013, in a 1–1 draw against Gloria Bistrița.
