He lost to Sakuraba the "Gracie Hunter" he hasn't really been the same since the second Shamrock fight. Also in this fight with Hughes they won't allw Gracie to wear his trademark Gi, so that puts Hughes at an advantage. Royce was great in his time but I think he was ruined by Shamrock in that rematch since he has never looked the same since.

He never LOST in a UFC match that he fought in. He lost in the UFC once by default because he couldn't advance due to the exhaustion from beating Kimo.
