Russia's Daria Kasatkina's management say a flag error could have "strong implications" for the player after she was wrongly listed as representing Spain at a WTA Tour draw ceremony - leading to suggestions she had switched allegiance.
BBC Sport has been told Kasatkina, who has criticised Russia's LGBT rules and opposed the war in Ukraine, has not switched allegiance.
The appearance of the Spanish flag next to the world number 11's name during the Abu Dhabi Open draw attracted attention, sparking online discussion that she had decided to stop representing Russia.
"It is incorrect and we can categorically deny she is switching to Spain," Kasatkina's management told BBC Sport.
