Was Maidana trunks an hindrance for him?

It was noticeable that he kept tugging at it, for which he lost focus at times, and kept getting hit unguarded. Can a boxer change trunks between fights? I have never seen it happen before, but can it? Just get a team member to bring a new one..as long as it happens between rounds and in the i min limit. It was annoying the hell out a me i might add. NB: I think Khan fought beautifully, but he just need to pace himself better and pick his shots better. I observed that, once in a while, he would get wild and sloppy and run into punches, but most of all, i was impressed with his chin. Peace to boxingfans.
