Thai League 1 will resume next month and finish on March 28, officials said on Friday.
Thai League Co acting chairman Korrawee Pritsananantakul said after a meeting with Thai League 1 and 2 clubs that the two leagues will resume on Feb 6.
However, a rearranged T1 game between champions Chiang Rai United and Port will take place on Jan 31, he said.
All matches in T1 and T2 scheduled for this month were postponed after a new surge in coronavirus cases as the Centre for Covid-19 Situation Administration (CCSA) prohibited certain activities.
Korrawee said the season would not be extended with T1 ending on March 28 and T2 on March 31.
As a result, there will be five extra midweek matchdays in T1 and seven in T2, he said.
Matches will be held behind closed doors and under strict Covid-19 protocols with a maximum of 180 people including players allowed at the stadium in each match, Korrawee said.
He said teams in five most at-risk provinces -- Samut Sakhon, Chon Buri, Rayong, Trat, and Chanthaburi -- must play their home games at other venues until further notice.
Teams are allowed to use five substitutes until the end of the season, he added.
The season was suspended for six months last year and resumed in September before it was halted again this month.
BG Pathum United are runaway T1 leaders with 44 points, 10 ahead of Port who have a game in hand. Most teams have 14 games remaining this season.
