The NBA has stated that Kawhi is injured and the Clips sitting him is consistent with league policy. The NBA fined them for:
“The NBA has fined the Clippers $50,000 for statements, including by head coach Doc Rivers, that were inconsistent with Leonard's health status.”
The NBA doesn't want the perception out there that healthy players are sitting out games especially nationally televised games. So if team officials are going to talk about it they better get their language right or else they are going to be fined.
