Disgraceful!

The incident which took place between a coach and the umpire during a Under-16 National Cricket Championship match is a disgrace to cricket.
The use of 12th man in cricket, which was the cause behind the dispute, could be quite tricky and we have seen misunderstanding over this even between international players and officials. But they never take the matter to that extreme.
Being a former student of Discovery Cricket Academy, I believe the matter should be treated very seriously by the cricket authorities.
