Buriram United return to action in Thai League 1 on Saturday when they host Suphanburi after their players completed 14-day quarantine due to a Covid-19 case.

The season resumed on Sept 12 following a six-month break because of the coronavirus pandemic.
However, just before the restart, Buriram's new signing Akbar Ismatullaev of Uzbekistan tested positive for Covid-19 and the entire team had to enter quarantine.
Buriram coach Bozidar Bandovic said on Friday it would be difficult for the Thunder Castle who only had little time to prepare for Saturday's game.
"Suphanburi have already played two games [since the restart]," he said.
"But I believe our players are ready for the match."
Leaders True Bangkok United take on second-ranked BG Pathum United on Sunday.
"Our players are in confident mood," said Bangkok United assistant coach Watsapol Kaewpaluek.
"It will be a good test for our team as BG Pathum are strong in defence."
