In his early career, Prieto played for Club Atlético Bella Vista, Club Social, Deportivo y Cultural Español, Club Atlético Independiente, Club Atlético Nueva Chicago and Club Atlético Belgrano, with a small Greece stint in between (with AEK Athens FC).
In 2005–06, he moved abroad again, joining Clube Atlético Mineiro in Brazil, with subsequent spells at Club Sportif Sfaxien and C.D. Santa Clara. Prieto had agreed to terms to play for the Newcastle United Jets FC in the 2007–08 season of the Australian A-League, but apparently reneged on his contract after having been signed as a direct replacement for Nick Carle who left the club at the end of the previous campaign.
After leaving, he signed with Ecuador's Club Sport Emelec, moving shortly after to Portuguese top division side F.C. Paços de Ferreira. During one sole season, he appeared in two matches out of 30 (a total of 43 minutes).
On 18 December 2009, Prieto was hired by Duque de Caxias Futebol Clube in Brazil. After appearing rarely during his only season with the club, spent in Série B, he returned to his country and joined lowly Sportivo Italiano.
