Muangthong United's eight-game Thai League winning run ended with a home loss to Chiang Rai United.

The Kirin began the match without Lucas Rocha due to injury. Shortly into the game, the club's other centre-back, Jesper Nyholm, was taken to hospital with a shoulder injury that will see him sidelined for the rest of the season. 

The injuries and the loss brings into doubt whether a third-place finish is possible, and next week's match against second place Bangkok United takes on a new importance.
