Jens Pulver
After his second victory over Rumina Sato, Uno was recruited to fight for the UFC's Bantamweight (later renamed Lightweight) title against Jens Pulver. Throughout the fight, Pulver stopped Uno's takedown attempts and pressed the action on the feet. Uno, who had earned a reputation as being "unflappable", began to show frustration for the first time in his career as Pulver neutralized all his offensive efforts. Pulver took a majority decision win in the fight.
