the more u read about what? heresay and inconclusive evidence?
Nope. My own speculation. It's pretty hard to headbutt a shorter opponent DOWNWARD and give him/her a 3 inch cut on the forehead.
It sounds like she tried to headbutt him upwards and cut herself on his chin.
I could be wrong, but it seems weird that any man would go through the effort of headbutting a shorter woman. Then again, Chad is a weird guy
