With Buriram United having secured the Thai League 1 crown, the focus will now be on the other end of the table.
Lampang and Nongbua have booked tickets to Thai League 2, and four teams will fight to avoid the last relegation spot in the final three games.
Lamphun Warriors, who are third from last, have 27 points, two behind Khon Kaen, Nakhon Ratchasima and Prachuap.
On paper, Lamphun have an easy task and should have few problems when they host bottom club Lampang, who are making a quick return to T2, today.
Also today, Khon Kaen travel to Police Tero, while Nakhon Ratchasima visit Chonburi.
Nakhon Ratchasima coach Teerasak Pho-on said he was confident that the Swat Cats would remain in the top flight. "I have told my players to do it for Korat people," he said.
Prachuap, who lost to Buriram in the League Cup semi-final in midweek, are at home to second-placed Bangkok United tomorrow.
Buriram, led by Thailand forwards Supachai Chaided and Suphanat Mueanta, host Port.
