Floyd lost a point for "elbowing"
Castillo lost a point for "hitting on the break"

How are those fouls in any way related to "pushing?" Khan's "pushes" wouldn't even be an issue had the points not been deducted. The "pushing" was so insignificant that Peterson actually thought Khan was docked points for pulling his head down. It didn't bother him in the slightest.

Clearly "pushing" is such a minor offence that no-one can even recall previous cases of point deductions.
