Short version is it will still be a judgment call by the refs while the game is going on.
After the game it will be reviewed by the league similar to Flagrant Fouls and fines will be given out.
One note from ref camp: NBA is close to finalizing policy on flopping. Will not carry in-game penalty. Will be reviewed after. Poss fine.
