FIFA says it is investigating the case but has not decided if Thailand broke rules, which could allow Palestine to advance instead.

Thailand eliminated Palestine on penalties in March after a second-leg match in the West Bank. It was the first competitive international match played in Palestinian.

However, FIFA is studying whether Thailand midfielder Sucharit Chanthakul should have served a suspension when he played in the first leg.

Thailand is scheduled to play Bahrain in a two-leg series on June 19 and 23 in the second round of Asian qualifying.
