I think he will get fined. Not suspended though. Wait did he even get off the court? If not im not sure hes even fined.
They fined Vernon maxwell when he got in a fight with a fan who not only was using racial slurs but making fun of the fact that his baby girl had just died. And the NBA gave him like the biggest punishment in league history at the time after Kermit Washingtons. I think he got 10-15 games and a 20 thousand dollar fine.
If Stern will fine you for going after a guy who insulted your race and laughed at your dead baby he doesnt care about Mutombos feelings in this. If Mutombo stepped into the stands even a foot I think Stern fines him.
