You have not been charged yet and very possibly a formal complaint has not been made. Unless the person you hit has reported it to the police nothing will be done. At least not by the police, the football league are another matter.
They may well penalise you or your team for misconduct.
I suggest you talk to the man you hit and apologize , if he has not made a formal complaint about it to the police you will not be facing a criminal charge .You can ask him if he is pressing charges , I suspect he will say No.
To be honest the police have more to worry about than an argument on a football field, I dought they will be interested.
