Former giants Police Tero's inability to defend an early goal from Michael N'Dri in a 2-1 loss to Ratchaburi last night has left them on the verge of demotion from Thai League 1.
Soo Il-Kang converted a 17th-minute penalty and an injury-time winner by Nerijus Valskis of Ratchaburi left Police six points behind Sukhothai, who are in 13th place, with only two games remaining.
In case Police pull off a tie on points with Sukhothai at the end of the season, they will survive in the top flight. Police beat Sukhothai 2-1 in two games in the league.
An injury-time strike by Sanukran Thinjom helped SCG Muang Thong United salvage a 3-2 victory away at Sukhothai after squandering a two-goal advantage.
Jakson Coelho, finding the net in the 20th minute, ensured that Muang Thong went into the break with a 1-0 and they picked up their second through Heberty Fernandes before the hour-mark.
However, a brief lapse in concentration on the part of the Kirins' defenders saw Sukhothai cancel out both goals as John Baggio scored with a long shot in the 64th minute and Nelson Bonilla converted a penalty six minutes later.
Sanukran's strike in the fourth minute of injury-time also helped Muang Thong wrest back third spot in the table from Port, who blanked relegated Navy 5-0 late on Saturday night.
Suphanburi assured themselves of another year in the top flight with a 2-0 victory over visiting Bangkok Glass last night.
Goals from Tanasith Siripala (28th minute) and Chananan Pombuppha (70th) left the Glass Rabbits once again within striking distance of those trying to escape relegation.
Chiang Rai started preparing for their final games of this year's FA and League Cup events later this month by routing second division-bound Ubon UMT United 4-1 last night.
