No way he did it in sparring. For starters, most pros use 16 oz gloves in sparring so hardening his wraps would be dumb. Hed just elect to spar with 14oz gloves. Sparring isnt about beating up and finishing off the guy in front of you, its about sharpening your own tools. If he hurt Rashad like he says, and thats what his intentions were, then he would have finished him off, which he didnt. In sparring, you get hit with good shots, just like in a fight but Margarito would have nothing to gain if his sole purpose in sparring was to ko everybody.
