LAS VEGAS - Floyd Mayweather Jr. put on a virtuoso display of boxing skill, winning by unanimous decision over "Sugar" Shane Mosley on Saturday night to keep his perfect record intact. Mayweather (41-0, 25 knockouts) gave a masterful effort in his most dangerous fight in several years against the 38-year-old Mosley, who put Mayweather on his heels with several rocking punches in the second round of their welterweight bout. Mayweather regained his composure and thoroughly outboxed the veteran champion.

It won't be official for two weeks, but Mike Jones will make his debut at New York's Madison Square Garden on Dec. 3 against Argentine Sebastian Lujan. The welterweight bout will top the undercard for the Miguel Cotto-Antonio Margarito rematch. In June, the former Mount Airy resident remained undefeated at 25-0 with an easy second-round technical knockout of Raul Munoz at the Asylum Arena in South Philadelphia. Jones' promoter, Bob Arum of Top Rank, said the 28-year-old will be placed on a short list to face Manny Pacquiao in 2012.

As boxing debates go, you could do worse than trying to determine which is the more remarkable feat: 46-year-old Bernard "The Executioner" Hopkins trying to become the oldest holder of a widely recognized world championship, which could happen when the seemingly ageless North Philadelphian bids to dethrone WBC light-heavyweight titlist Jean Pascal on May 21 in Montreal, or Manny Pacquiao, 32, winning belts in eight weight divisions, and seemingly...

MANNY PACQUIAO might meet an old foe in a new place in September. Promoter Bob Arum said he is trying to put together a fifth fight between Pacquiao and Juan Manuel Marquez and shopping it to casinos in Macau and Singapore. Marquez would be the most likely opponent for Pacquiao, though Arum indicated earlier that Timothy Bradley - who won a disputed decision over Pacquiao last year - is another possibility. Marquez knocked Pacquiao out in the sixth round in December, flattening the Filipino fighter with a right hand that left him face down on the canvas for 2 minutes.

FLOYD MAYWEATHER JR. has taken his quest for a fight with Manny Pacquiao to Twitter. The unbeaten Mayweather publicly challenged and taunted the Filipino superstar yesterday, daring Pacquiao to meet him May 5 in Las Vegas. "Manny Pacquiao I'm calling you out let's fight May 5th and give the world what they want to see," Mayweather tweeted. Pacquiao met with his promoter Bob Arum in the Philippines, the Los Angeles Times reported, and decided the best course for pursuing a fight date against Mayweather is to schedule it for late May, or, ideally, June 9. Mayweather faces a June 1 date to report for an already-delayed 90-day jail term in a domestic violence case, but Arum said he'd be "willing to chip in for lawyers' fees" to get that date moved again so a June 9 bout could occur.

The proposed megafight between Manny Pacquiao and Floyd Mayweather Jr. was thrown into jeopardy yesterday with a demand by Mayweather's camp that the fighters be subjected to Olympic-type drug testing in the weeks leading up to the bout. Mayweather's manager said the fight would not go on if Pacquiao didn't agree to blood testing under standards followed by the United States Anti-Doping Agency. "There is no fight without Olympic-style random drug testing," Leonard Ellerbe said.

OF THE HUNDREDS of millions of people around the world who maintain at least a casual interest in Manny Pacquiao, the level of enthrallment for the most part neatly separates those who follow him strictly as a record-breaking boxer from those who have come to regard him as a cultural and societal icon, a curious mishmash of politics, entertainment, philanthropy and, to hear some tell it, a mad scientist's lab experiment. Oh, fight fans like to believe they know every pertinent detail about Pacquiao (52-3-2, 38 KOs)

Western Kentucky and new football coach Bobby Petrino will be switching leagues after his first season with the Hilltoppers. Conference USA commissioner Britton Banowsky said Monday that Western Kentucky will officially join the league July 1, 2014. "The tradition of the university and its athletics success is truly remarkable," Banowsky said. "The men's basketball program has made seven NCAA appearances since 2000, the women's basketball program has advanced to three NCAA Final Fours and football went to a bowl game last season in just its fourth year in the BCS. " C-USA, however, is losing Tulsa.

LAS VEGAS - The idea of Manny Pacquiao being knocked out cold was shocking enough. The sight of him face down on the canvas, unresponsive even as bedlam broke out all around him, was positively frightening. Pacquiao's wife, Jinkee, broke down in tears and tried to get in the ring to aid her downed husband. Juan Manuel Marquez didn't even look. He was already busy celebrating the knockout of a lifetime. This was boxing at its brutal best, a toe-to-toe welterweight slugfest late Saturday night that was destined from the opening bell to be decided by fists instead of judges.

NORTH CAROLINA said basketball coach Roy Williams' surgically removed kidney tumor was not cancerous, though he will have a biopsy to ensure a second kidney tumor is also benign. In a news release Tuesday afternoon, the school said tests have determined the tumor removed last week from Williams' right kidney was an oncocytoma, which is a benign growth often indistinguishable from kidney cancer on X-rays that doesn't spread like a cancerous tumor would. Williams also has a tumor on his left kidney, but according to the school, doctors say there is "a good chance" that growth is the same as the one removed Sept.

USA Swimming banned coach Rick Curl for life for an improper relationship with a teenage swimmer in the 1980s, another ugly chapter in a sexual abuse scandal that rocked one of America's most successful Olympic sports. Curl, who ran one of the nation's largest swim clubs near Washington, D.C., and coached 1996 and 2000 Olympic gold medalist Tom Dolan , was scheduled for a hearing Wednesday before the National Board of Review. But he informed the governing body he was waiving his right to challenge the case.

Three compelling fights in the last eight years still haven't resolved the rivalry between Manny Pacquiao and Juan Manuel Marquez . So they're going at it a fourth time on Dec. 8 at the MGM Grand in Las Vegas. Pacquiao (54-4-2, 38 knockouts) and Marquez (54-6-1, 39 KOs) fought to a draw in 2004, and Pacquiao won by decision in 2008 and again last year. Marquez and many fans still believe he won all three fights, while Pacquiao says he clearly won the last two. SNOWBOARDING: Two-time Olympic gold medalist Shaun White , 26, faces charges of public intoxication and vandalism, accused of drunkenly destroying a phone at a Nashville hotel.

The International Tennis Hall of Fame in Newport, R.I., is investigating allegations that former doubles champion Bob Hewitt sexually abused girls he coached, an inquiry that could result in expulsion from the Hall. Hewitt, 72, won all of the Grand Slam doubles during his decades-long career in the 1960s and 1970s and was inducted into the Hall in 1992. He lives in South Africa and has not been charged criminally. Among Hewitt's accusers is Heather Conner, of West Newbury, Mass., who has spoken publicly before and agreed to be identified.

WHAT a difference a few days can make. Less than three weeks after Floyd "Money" Mayweather — the sports world's highest-paid athlete — went to jail as part of his 90-day sentence for a domestic violence conviction, several things have changed. His chief rival, Manny Pacquiao — the world's second-richest athlete and long rated as the best pound-for-pound boxer in the world — unceremoniously lost. And Mayweather, a five-division world champion and holder of eight world titles himself, also lost — not a match but rather his bid to leave jail early as a Las Vegas judge denied his motion protesting the lockup's bad food and lack of workout space.
