Football's governing body is "looking into" a new video of Croatia defender Domagoj Vida in which he appears to again say "Glory to Ukraine!".
The video was posted online after the win against Russia that took Croatia into a semi-final against England.
The 29-year-old, who used to play for Dynamo Kiev, has already been warned by Fifa for a previous clip, which led to coach Ognjen Vukojevic being sent home by Croatia.
Fifa outlaws political statements.
Croatia play England in their World Cup semi-final on Wednesday (19:00 BST).
The first video drew criticism in Russia as the phrases used had previously been used by anti-Russian politicians in Ukraine.
Vida, who scored an extra-time goal against Russia and also converted a penalty in the shootout, later apologised.
In the second clip, Vida can also be heard to say "Belgrade burn".
Earlier in the tournament Switzerland trio Granit Xhaka, Xherdan Shaqiri and Stephan Lichtsteiner were fined by Fifa for breaking rules over political celebrations in their match against Serbia.
A provocative statement?

In itself, "Glory to Ukraine" is no more offensive than "Vive la France" or "Viva l'Italia" - it is a proclamation of support for Ukraine's independence and identity.
Given the recent hostilities with Russia, it has become strongly associated with critics of the Kremlin's policy.
The chant - and the response to it, "Glory to Heroes" - honours fighters against Russia-backed separatists in eastern Ukraine and those who were earlier involved in an uprising against pro-Russian President Viktor Yanukovych.
This appears to be the reason why some in Russia felt the video was aimed against their country.
"Our demands are legitimate, sport is outside of politics, and therefore Vida should get out of Russia!" said one Twitter user.
But Ukrainians accused Fifa of siding with Russia and flooded the football body's Facebook page with declarations of "Glory to Ukraine".
