A boxer simply couldn't wait for his fight on Saturday to start going after his opponent ... 'cause he straight-up shoved the hell outta the guy during a face-off -- forcing him to fall to the ground!!
The wild moment happened between super featherweights Michael Gomez Jr. (18-1) and Levi Giles (13-0) on Friday ... as part of the weigh-ins for the Lawrence Okolie vs David Light card.
Video shows Gomez Jr. lead with his head as he goes full steam ahead toward Giles .
