Thana Chanabut, Chenrop Samphaodi and Siwapong Charoensil have been left out of Thailand's 23-man World Cup squad due to injuries after coach Kiatisak Senamuang announced his team for the match against Australia tomorrow at Rajamangala National Stadium.
Midfielder Sarawut Masuk, however, has recovered in time to make the squad.
Thailand and Australia will battle it out in their fifth Group B match of the final phase of Asian qualifiers for the 2018 World Cup in Russia.
Saudi Arabia lead the group with 10 points, followed by Australia (eight), Japan (seven), the United Arab Emirates (six), Iraq (three) and Thailand (zero).
Thana scored Thailand's only goal in the campaign in the 3-1 loss to the UAE.
Thailand have already lost right back Narubadin Weerawatnodom who suffered a shoulder injury during training last week.
The top two teams of Group A and B qualify for Russia 2018. The two third-placed sides meet in a play-off with the winners facing a Concacaf team for another berth.
