Hard contact, no foul... You know what happens next...

Agreed, if you have paperwork for your state, it should include the post game incident.

If you don't have paperwork for your state for ejections, you should still call or email them with a report of the post game incident.

If you have an assigner for this game, he/she should get a full report.

Edit: I just realized this was MS boys. I'm going to add that if there is no assigner, then the AD needs to be copied on your report to whatever organization oversees MS basketball in your area (state, conference, UN, whatever). That's obscene behavior for a MS coach.
