Domagoj Vida says his pro-Ukraine comments in a social media video were not a "political message", with the Croatia defender having avoided a World Cup ban.
FIFA warned Vida over his conduct after he and former Croatia international Ognjen Vukojevic appeared in a video after the quarter-final shootout victory over hosts Russia.
Vida was filmed using the phrase "Glory to Ukraine", which has been used by Ukrainian anti-Russian nationalists, with FIFA's disciplinary code prohibiting "political slogans in any form".
FIFA confirmed on Sunday that Vida has been given a warning , meaning the defender will be available for selection when Croatia face England in Wednesday's second World Cup semi-final.
