So it looks like Riot is waiting for stuff to calm down in Ukraine, but its only escalating and doesn't seem like there will end soon.
Best case scenario for Gambit will be to play without representing org and Russia, but there could also be visa problems as some EU countries stopped issuing them to Russian citizens, I can see whole Schengen stopping all but political refugees from entering by the time Masters start, that would effect more teams that have Russian players.
Also Russia themselves could stop players from leaving as they might get conscripted. Or just stop emigration in general as its big problem there right now.
