What it sounds like, but seems to have been omitted from her report, is that those players who have been contact-traced to have been in "close contact" with positive Covid players (I assume) have been in quarantine, so if those players pop positive tomorrow or Sunday/Monday the game is still on, as those players (I assume) have been in quarantine.
The issue becomes if a player pops positive who was NOT deemed to have been in close contact with the already positive players...things might change.
