His Wikipedia page says he was a Co-Champ after going to a draw with BJ Penn for the title, but why was this never resolved? Wouldn't it have made sense for a rematch to happen later on to unify the belt? Is this the only time in UFC history where there was technically two champs in a division without the use of Interim belts? This fight and the events surrounding it are some of the strangest anomalies the sport has ever seen and I doubt we'll ever see anything like it again. I still question the legitimacy of Uno's supposed championship, because I can't find any official recognition anywhere. And as a side note, talk about a waste of potential in regards to all these old Lightweight guys like Penn, Pulver, Uno, etc...they could of done so much better if they stuck to fighting guys their own size at FW or BW.
