I don't see this as a fight though, more as a sucker punch. Let me put it this way: if the initial "get off me" arm push by W43 resulted in no reaction by G2, would you give W43 a tech? I wouldn't. I would have a word with her and let my partners know she was on a short lease but nothing more. Now, I am fine giving W43 a tech for an action that resulted in a "fighting" re-action from G2, but I would not eject W43 because she is not actively participating in a fight.

1. Flagrant tech on G2 for the punch.
2. Unsporting tech on W43 for the initial arm thing.
3. Penalize the coaches as needed.
