Floyd Mayweather Accusers -- The Cracked Bones [Photos]

A broken arm ... a snapped pinkie ... and evidence of extreme torture -- just a few of the injuries suffered by one of the men allegedly beaten by Floyd Mayweather's crew ... and TMZ Sports has the X-rays.

We broke the story ... two men have lawyered up, claiming Mayweather ordered them to be beaten to a pulp recently because he suspected they stole jewelry from his Vegas home.

One of the victims had X-rays taken after the alleged incident and they show a variety of painful injuries, including:

-- Broken right pinkie
-- Severe swelling of the left hand
-- Broken left ulna
-- Cracked right ulna
-- Multiple fractures in left hand that required pins to reset the bones

We're told the left arm was so badly broken, doctors drilled into the bone to attach a titanium plate so it would reset.

The men claim Mayweather was present during the attack, but it's unclear if the boxing champ actually participated in the beating.
