Texas: Floyd Mayweather has no plans to return to the ring after hanging up his gloves undefeated last September, but he is finding opponents as a promoter more difficult to manage.

That was the case on Monday as reigning World Boxing Association super lightweight champion Adrien Broner stormed out of a Washington news conference to advance his April 1 title bout against Britain's Mayweather-backed Ashley Theophane.

"(Screw) those guys. They're coming to dethrone me," Broner said. "They are my enemy right now. I'm going to beat the (hell) out of Ashley. Fight ain't going four rounds. Nine minutes is too much. "I'm going to torture this guy."

Broner, 31-2 with 23 knockouts, chattered at his English rival and took off after that without staying for questions, leaving Mayweather to explain how an event that began an hour late came to such a premature end.
