Very, very disturbing situation

[BigDave]

Last Thursday, I had a boys varsity game. Rough first half with 25 fouls called. With 4 min. to go in the half, we have a crash and as I'm hustling in to make sure things go smooth, A1 stands up and flexes at B1. I say to him "Don't you taunt him." I thought it was a good piece of preventive officiating that possibly diffused a situation. No other problems in the first half.

During the intermission, home coach and principal come into the locker room with a question for me. The player I told not to taunt told his coach that I called him a MFer. I was shocked! I told the coach exactly what I said and said the kid obviously heard me wrong. They leave.

The second half is much more calm and team A wins by 20. After we shower and get dressed to leave, I asked to AD to escort us out just in case. When we get outside, everyone is gone so I was relieved. Well, today I get a call from my assignor and he tells me this kid's mother is pissed! I have to call the AD tomorrow and tell him my side of the story.

Here's my question. What should I do in this situation? I know what I said and I'm not going to explain to fifty people to try and prove my innocence. I will talk to the AD and my assignor, but I don't think I have any responsibility to talk to a parent. I know she is protecting her kid, but her kid is wrong. What do I do?
