He played internationally for the Croatia national team from 1940 to 1943 and with Yugoslavia's national team in 1946.[4] He was also part of Yugoslavia's squad for the football tournament at the 1948 Summer Olympics, but he did not play in any matches.[5]
Kacian played for HAŠK, Hajduk Split before moving to Dinamo Zagreb.[6]
He made his debut for the Jozo Jakopić-led Banovina of Croatia in a December 1940 friendly match against Hungary and earned a total of 10 caps scoring no goals. He played the other 9 games under the flag of the Independent State of Croatia, a World War II-era puppet state of Nazi Germany.
