Chicago Bulls big men Nikola Mirotic and Bobby Portis got into an altercation in practice on Oct. 17. Nikola ended up on the worse end of a fist and was sent to the hospital with several facial fractures.

After Bobby found out he got suspended for 8 games, without pay, of course, he tried to apologize to Mirotić but was rejected.
Then Bobby said:
To say your dream is taken away from you after you literally fight with your teammate for minutes and put him on the injured list for weeks is beyond dumb to me.
My rule proposal would be;
If a player disables his teammate from competing by deliberately injuring him, that player isn't eligible to play until the injured player/teammate is cleared from the injured list by team's medical staff and that decision is approved by the NBA's medical staff.The NBA's medical staffs approval IMO is necessary in the cases where for example, a star player hits a benchwarmer and the team fakes that a benchwarmer is cleared to play, even though he is not or psychological doesn't feel ready to play.
I know that teammates will sometimes get overly competitive, it is in the nature of the conflict/sport. I was guilty of it too, I admit that when I was 15, I've put a knee in front of my friend, hit a side part of his knee after he beat me off the dribble, and he missed a week or so with a minor knee contusion. Both of us had the same status then, although I thought he was a bit better, as we were fighting to make the team. I felt really bad afterward and took few valuable lessons from it. I think that a wrong message is sent out to the kids by letting Bobby play before Nikola is game ready.
