Hey Tatsuya-boxers, not briefs!
Update: If O'Brien can't make weight, there is a chance that he will be replaced on virtually no notice by Ricco Rodriguez, assuming Ricco can get down to 205 in time. This is according to an interview he did today with Sherdog's Japan reporter, Tony Loiseleur.
Update 2: Junkie says O'Brien missed weight by 1 kg, or 2.2 pounds. He gets one more try.
