The 2019 MSI Play-In schedule has been changed. 

The schedules for the MSI Play-In Stage which was to be held on May 1st-4th has been changed due to a state funeral for the former President of Vietnam, Le Duc Anh (Lê Đức Anh). The state funeral has been scheduled on May 3rd-4th and any kind of 'entertainment ' is prohibited during the official two-day mourning. As a result, some minor adjustments for the Play-Ins were inevitable. 

Round 1 which was previously planned to have 6 games a day during May 1st to 4th, will now have 8 games a day on the 1st, 2nd, and 5th. And Round 2 which was to be held on May 5th-7th will now feature 2 matches on the 6th. Schedules for the 7th has not been changed. Due to these adjustments,  teams that participate in the Play-Ins Round 1 might have to deal with possible fatigue issues.
