Second-placed Bangkok United must beat relegation contenders Lamphun Warriors tomorrow to keep alive their slim hopes of snatching the Thai League 1 title from Buriram United.
Defending champions Buriram have 64 points, nine ahead of Bangkok with five games remaining.
The capital side stunned Buriram on Tuesday when they rallied from two goals down to win 4-3 and hand the Thunder Castle their first loss of the season.
While Bangkok United will start favourites at Lamphun, it could be a tricky assignment for the Angels as the Warriors need points for survival.
Buriram will try to bounce back from the shock loss to Bangkok when they host bottom side Lampang.
Thunder Castle should have few problems as Lampang are preparing to make a return to Thai League 2.
The Emerald Chariots are nine points from safety.
In today's action, fourth-placed Muang Thong United will be looking to continue their good run when they host relegation strugglers Khon Kaen United.
Prachuap, who sit one place above the drop zone, are at home to Nongbua, who look set to go down to the second tier.
