According to a Cage family friend, the man who unleashed the beating -- Weston's former trainer Kevin Villegas -- has since been fired ... and has become the target in a police investigation.

But law enforcement sources tell us, the LAPD is also investigating Weston himself -- after he allegedly incited the fight by attempting to roundhouse kick Villegas outside the Hollywood restaurant where the incident took place.

Weston hasn't filed anything yet with officials -- but he plans to make his move as soon as possible.
