What jr. welterweight boxing match did I see last night (Chicago)?

I just caught the end of it .I usually watch UFC but this looked interesting. There was a guy named Daiz and some bigger y italian guy that clowned around alot that kicked his aZZ. If you could tell me what this series of boxing is called and what the italians name was (macheraggi or something) that would be great. Lennox Lewis was commatator. Thanks.
