Heading into Friday's clash at the Sri Nakhon Lamduan Stadium on the back of a 2-1 opening-day win over Army United last Saturday, the Twin Qilins took the lead after just eight minutes when Adnan Barakat received the ball on the edge of the area from Dagno Siaka and unleashed a left-footed strike that looped just inside the top corner.
Shortly after, the visitors thought they had doubled their lead when Piyaphon Buntao broke free down the right and whipped in a cross that was headed home by Roland Linz, only for the effort be chalked off for offside.
Despite their opponents' strong start, Sisaket equalised a minute before the half-hour mark when Kittiraj Sanor latched onto a visionary through-pass down the left and cleverly clipped the ball past the onrushing Weera Koedpudsa.
Although Muangthong continued to dominate proceedings, they were unable to find a way past the opposition defence and it began to look as though they would have to settle for a share of the spoils.
However, a minute into injury-time, a right-wing cross from Siaka was headed back off the bar by Piyaphon, allowing Teerasil to nod home the rebound from two yards out to hand the defending champions all three points.
Slavisa Jokanovic's charges are next in action on Tuesday when they visit Urawa Red Diamonds in the AFC Champions League.
