Pretoria: Algeria striker Rafik Saifi was involved in an altercation with a journalist after his team was eliminated from the World Cup.
The incident following Wednesday's 1-0 loss to the United States happened at Loftus Versfeld in an area where media interviews are conducted with players.
A female reporter from an Algerian publication was heard shouting at Saifi, who left the stadium holding his lip and refusing to respond to questions.
FIFA spokesman Nicolas Maingot told a news conference Thursday morning that he'd heard about an incident after the Algeria match but had not received an official report.
He declined comment on the specific case, but said: "It's clear the values of fair play apply not only the pitch, but off the pitch as well."
Algeria finished at the bottom of Group C with just one point and was eliminated from the tournament.
