Ivan Perisic will miss Croatia's Euro 2020 last-16 clash with Spain after testing positive for COVID-19.
The Croatian Football Association announced the veteran winger's result on Sunday (AEST) and said he will spend the next 10 days in self-isolation.
All other national team members and staff tested negative, they said.
The rest of the team will fly from their base in Pula to Copenhagen on Monday, with their last-16 match against Spain set for Tuesday.
Perisic has scored two of Croatia's four goals at the Euros, with the Inter Milan man providing the equaliser in their 1-1 draw with the Czech Republic and netting the final goal in the 3-1 defeat of Scotland.
Perisic also provided the winning margin in Croatia's 2-1 victory over Spain at Euro 2016 with a goal in the 87th minute.
