This year’s Asian Le Mans Series has been reduced to a four-round season following news that next month’s event in Thailand has been canceled.

Series officials confirmed Sunday that the Three Hours of Buriram, which was scheduled to take place at the brand-new Buriram International Circuit on Nov. 21-23, will not go ahead as planned.

“After consultation with teams and stakeholders, organizers of the Asian Le Mans Series have made the decision to remove the Thailand race from 2014 calendar in order to focus on delivering a successful final race in Sepang as well as being well prepared for 2015 season,” a statement from the series read.

The news comes on the heels of last weekend’s race in Shanghai, which again saw a single-digit grid for the third consecutive event this year.

This year’s season will conclude in Sepang on Dec. 5-7, with plans to release the 2015 calendar shortly, which will see improvements in scheduling with the goal of increasing car counts.
