Career
Born in Hrvatska Dubica, Braun began playing as a youngster for the local club NK Una. While playing for Una in Bjelovar he was spotted by NK Dinamo Zagreb"s scouts who invited the talented left back to come to Zagreb for a trial in late 1960. Led by the prolific goalscorer Slaven Zambata the team also finished runners up in the 1962-1963 Yugoslav First League.
Braun"s good performances earned him a call-up for the Yugoslavia national football team and he had his international debut in a crucial 1964 European Nations" Cup qualifier against Sweden on 18 September 1963.
Although Braun"s club teammate Zambata scored to put Yugoslavia 1–0 up in the opening minutes, the game eventually ended in a 3–2 defeat. In early 1964 Braun was seriously injured in a car accident.
He then spent the entire 1964-1965 and 1965-1966 seasons recovering away from the pitch. He tried to return to football in the following season and even had 15 appearances in the 1966-1967 Yugoslav First League, but his good form never returned.
After a single league appearance in 1967-1968 Braun decided to retire from the game in his mid-twenties.
