Roy gave an interview to ESPN where he explained the accusation in detail. If you want to watch go to http://espn.go.com/boxing/
For those who dont here is a bit of what he said:
"They let the guy wrap his hands with a cast and he hit me behind the head"
"If the ref would have left me alone I would have spanked him"
"We took the box away from over there. He wrapped his hands with gauze that came out of a box. It says clearly on the box that it has adhesive on it. The adhesives on a gauze is not allowed in any form of boxing. You cannot use gauze with adhesive on it. You wrap your hands two hours early with a gauze that has adhesive on it and you let it get a little bit wet and you got a cast basically"
"It aint no accusations its fact"
"We are pursuing it but you have to remember this didnt happen in this country. Its a little more difficult to pursue it because they dont want to make their country look bad"
