If he’s vaccinated, he must have a breakthrough case, which would be incredibly unlucky.
If he’s not vaccinated, then he’s either out for a week due to close contact, which means he won’t miss any of the conference finals, or significantly longer if he’s infected, in which case who knows how long it will take him to recover.
Odds are he’s not vaccinated (because breakthrough cases are pretty rare at this point given how down cases are right now). Hopefully for the Suns they don’t have an outbreak on their team.
