2010 Thai Division 1 League

2010 Thai League Division 1 is the 13th season of the League since its establishment in 1997. It is the feeder league for the Thai Premier League. A total of 16 teams will compete in the league.

League Expansion
It was announced at the end of the season that the TPL would increase the number of teams for the start of the 2011 Thai Premier League season. Therefore, at the end of season the three teams in the Thai Premier League that finished the season in the bottom three places (14th, 15th and 16th) would face the fourth, fifth and sixth teams from Division One in a promotion/relegation series.

The six teams will be divided into two groups of three. They will meet each other in their group on a home-and-away basis with the winner of each group earning spots in the top flight next season.

It was also announced somewhat belatedly that the teams that finished in the bottom four places, who would normally be relegated would play in an end of season promotion/relegation series against the teams coming 3rd and 4th in the 2010 Regional League Division 2 championship stage. Games would be played on a home and away basis to decide who would play in the 2011 Thai Division 1 League.
