A decision on whether next week's Clasico between Barcelona and Real Madrid can go ahead at Camp Nou is set to be made on Thursday, Royal Spanish Football Federation (RFEF) president Luis Rubiales said.
Violent scenes broke out in Barcelona at the start of the week after nine Catalan political leaders received long prison sentences for their roles in the region's 2017 referendum and subsequent declaration of independence.
A rally in the city has been called by pro-independence politicians for October 26, the day Barca is due to host bitter rival Madrid.
Barcelona's main airport was briefly closed on Tuesday due to the tension, with Spanish league officials raising concern the Clasico could be affected by protests.
One option would be to move the game to Madrid and for Barca to host the second Clasico of the season, but that was opposed by Blaugrana head coach Ernesto Valverde on Thursday.
There have also been suggestions the match should be postponed and an alternative date in the calendar found. Valverde thinks the game should go ahead as planned.
Rubiales said Barca and Madrid swiftly submitted their observations on the matter and the RFEF would be seeking to make an early decision.
"I can assure that we will work to try to have a resolution this evening, because there are people involved, supporters with booked trips, tickets, media, and that is what we have done," Rubiales said.
"Regarding the government, what I can say is that this is a matter of football, and it is the competition committee which has to decide. So the government hasn't contacted us or asked for one or another thing."
