Meanwhile, holders Buriram United were held to a 1-1 home draw by Muang Thong United in Thai League 1 on Sunday night.
Uzbekistan's Sardor Mirzaev gave Muang Thong a 1-0 half-time lead and Thailand forward Suphanat Mueanta equalised for the Thunder Castle in the 58th minute.
Buriram's Supachai Chaided sent the ball into the back of the net in injury time only for it to be ruled out after a VAT check.
Buriram coach Masatada Ishii rued his team missed chance to get three points and said his men lacked sharpness up front.
The result left the Thunder Castle in fifth place with 11 points, only two adrift of co-league leaders Bangkok United and Ratchaburi.
