Ivan Anton Vasilj (born 5 April 1991) is a Croatian football player who plays for Zadar.
A captain of their U-19 team at the time,[1] he made his professional debut in the Prva HNL at 6 March 2010 against NK Karlovac.
A left-footed left back/winger, he went on to establish himself in the NK Zadar first team, featuring regularly in the second part of the 2010–11 season onwards.
In December 2012, the doping test after a match revealed the presence of the illegal cannabinoid JWH-018 in his body.
It was, however, ascertained, that it wasn't taken directly and willingly, possibly inhaled unwittingly somewhere in form of incense or air freshener, and therefore not punished harshly and he only ended up missing one match because of it.
