Outspoken Andrew Bogut faces possible punishment from basketball's governing body FIBA after Australia's acrimonious exit from the World Cup semi-finals in Beijing.
Video footage showed Bogut -- who was booed by Chinese fans throughout the tournament -- swearing several times as he trudged off court after Friday's defeat to Spain.
Bogut, 34, who riled the hosts with a tweet about Chinese champion swimmer Sun Yang in July, appeared to suggest that FIBA and its referees had favoured the Spanish team.
Spain won a thrilling semi-final 95-88 after double overtime and will play Argentina, winners over France, in Sunday's final.
The footage of Bogut swearing repeatedly and making accusations of favouritism was widely featured in Chinese media. Many reports called for FIBA to ban him.
"There's a lot of the guys in the locker room who gave their hearts and souls tonight," said forward Nick Kay.
"We definitely left it all out on the court."
