Born in Kranj, 20 km near Slovenian capital Ljubljana, Darko Ceferin started his refereeing career in 1992 and officiated his first 1st division match in 1996. In 2000 he got his FIFA badge. He was a premier referee but was demoted in 2011 and put in the first class, maybe that is why he retired at the end of that year.

Ceferin was promoted in June 2005 into a Premier Group of Referees and he refereed his 1st Champions League match December 2005 in Sevilla. (source: Darko Ceferin)
