LAS VEGAS— A Las Vegas judge issued an arrest warrant for Roger Mayweather today after the boxing trainer failed to show up for a court appearance on battery and coercion charges.

Mayweather, who coached his nephew Floyd Mayweather Jr. to victory in a September comeback fight against Juan Manuel Marquez, did not appear or have a lawyer present at a felony arraignment in Las Vegas Justice Court on Friday.
Judge Joe Sciscento issued the warrant after he called Mayweather’s name and case number from a list and nobody in the court acknowledged him. After issuing the warrant, Sciscento promptly moved on to the next case.
Attempts to reach Mayweather by The Associated Press were not immediately successful. Several phone numbers listed for Mayweather were disconnected. Representatives for Floyd Mayweather Jr. declined to comment, saying they did not represent his uncle and did not know how to immediately reach him.
Roger Mayweather, 48, was accused of attacking a female boxer he once trained, who told police that Mayweather attacked her Aug. 2 at an apartment Mayweather owned and was renting out.
The alleged victim’s roommate told authorities that Mayweather repeatedly harassed the boxer after she ended a training arrangement with him, and was unhappy that she was living in the apartment the previous five months, according to a police report.
The 26-year-old woman told police that Mayweather punched her in the ribs, and said she hit him with a lamp during a struggle. Police said she was treated by paramedics at the scene and was taken to a hospital for injuries including redness around her throat.
Mayweather had injuries on the head and the side of his face. It was not clear if he required medical treatment before he was taken to Clark County jail. He was later freed on $13,000 bail.
Mayweather boxed under the nickname “Black Mamba,” winning two boxing titles in different weight classes in the 1980s and 59 of 72 fights with 35 knockouts.
He made headlines in 2006 as his nephew’s trainer when he burst into the ring in the 10th round to challenge Zab Judah after Judah illegally punched Mayweather Jr. in the groin and back of the head. The incident sparked a melee between the fighters’ entourages that led to fines and the temporary revocation of licenses for Roger Mayweather and others.
Floyd Mayweather Jr., 32, has won six world boxing championships in five weight classes and is undefeated in 40 fights. He easily outclassed and overpowered Marquez during their Sept. 19 bout, leading many to believe he regained the mythical title of the world’s top pound-for-pound boxer.
