Fights will happen in s[ports especially contact sports. You always want your players playing at that edge. The lesson will be if on the same team can they get over it.

As much as the team could be playing on the school fields and with the coaches not sure it is truly sanctioned but this day and age is different. Me I say, coach takes care of it his way, which will hopefully be both yes both boys are running, as well as the team. Use this as a team building exercise and move on, if things cant move on and there is an underlying issue, coach has to use his judgement.
