He can't practice with the team in NY. While he could theoretically practice on the road, the team has deemed this not feasible. I'm pretty sure he forfeits salary for all games. Let me try to do some digging.
My article won't paste, but suffice it to say that I was in error. Kyrie only has to forfeit home game salary, plus the two games at MSG, and one game at Chase Center (SF). He loses approximately $380,000/game, around $15M total. He will be paid for road games (as of October) even if he doesn't play in them. So, he won't be hurting for money this year.
