I've got a flagrant 1. The reason the player turns his head is cuz his arm is being locked and he's wondering why the hell the official is not seeing it. I think his subsequent action warrants a flagrant 1 because I believe the contact is a result of trying to get his arm loose, not a premeditated action. And yes I know those words are not found in the F2 language. If you want to go F2 then eject the offensive player too for initiating an action which lead to 'fighting'.
