Champions Buriram United will receive the Thai League 1 trophy at their home ground Sunday night when they take on Khon Kaen United in their last match of the season.
The Thunder Castle were assured of their ninth top-flight title with two matches to spare on May 17 when Bangkok United suffered a shock 3-0 rout at the hands of Police Tero.
Buriram also completed a hat-trick of Thai League 1 crowns.
However, the northeastern giants, who had swept all three domestic titles last season, would have to be content with just the league top honours this time round.
They lost 2-0 to Muang Thong United in the League Cup semi-finals on Wednesday.
After the loss to arch-rivals Kirins, Buriram head coach Jorginho left the team with "mutual consent" with tonight's final game of the season still remaining.
