The move came after Thai Premier League leaders Buriram refused to release defenders Theerathon Bunmathan and Prathum Chutong for the tournament just a day after Kiatisak had included the pair in his 20-man list.
With the Thai team set to start their two-week training camp in Phuket today, the 41-year-old coach moved swiftly to replace the Buriram duo with Muangthong United left-back Suriya and Chonburi winger Krirkrit.
Krirkrit and Muangthong keeper Kawin Thamsatchanan are included as the Thai side’s only overage players for the September 19-October 4 under-23 tournament in Incheon, South Korea. The competition rules allow each squad to pick three overage players.
