LAS VEGAS (AP) -- A lawyer for boxer Manny Pacquiao says rival prizefighter Floyd Mayweather Jr. failed to appear for a court-ordered deposition in Las Vegas in a federal civil lawsuit alleging that Mayweather defamed Pacquiao.
Attorney Daniel Petrocelli says Mayweather didn't show Friday to provide sworn testimony despite federal Magistrate Judge Robert Johnston's ruling Thursday that he must appear.
Mayweather's lawyers didn't immediately respond to messages.
They argued Thursday that Mayweather needed to concentrate on training for a Sept. 17 fight against Victor Ortiz.
Petrocelli tells The Associated Press he'll seek a default finding that Mayweather defamed Pacquiao with statements accusing Pacquiao of taking performance-enhancing drugs.
The two are considered the best pound-for-pound fighters in the world. They've failed to agree to meet for what could be the richest bout in boxing history.
