I swear I saw OpTic vs XSET and DRX vs Leviatan games tomorrow instead of the 15th.
Did Riot change it or VLR just had an error?
the real reason is because of one of the PRX Players since yesterday are getting covid 19
source
so thats why riot moved prx guild match from match 4 to match 1 for helping one of the PRX players who getting covid can recovery for at least 1 day (if they lost against guid) after upper bracket match against guild
if riot still not make schedule change, prx probably will be play again tomorrow against fnatic/fpx after their match against guild
