The World Curling Federation (WCF) has extended its ban on competitors from Belarus and Russia until the end of the 2022-2023 season.
The ban was originally imposed after the Russian invasion of Ukraine in February but was due to expire at the end of 2022.
A meeting of the WCF Board has voted to extend the ban after concerns were raised over the participation of Russia and Belarus.
"Their involvement would damage the integrity of the events due to the ongoing conflict in Ukraine," a WCF statement said.
The extension was granted under WCF Rule C1(b), which includes a clause allowing the international governing body to take action.
"The Board of the WCF may remove a team or Member Association from any WCF event if, in the sole opinion of the Board, their presence at the event would damage the event or put the safety of the participants or the good order of the event at risk," the rule states.
