Dereck Chisora has been suspended indefinitely by the World Boxing Council for his behaviour before and after his fight with Vitali Klitschko.

British heavyweight Chisora was involved in a brawl with countryman David Haye at the news conference after his defeat by the Ukrainian in Munich.

Dereck Chisora and David Haye may face life bans for their Munich brawl says the British Boxing Board of Control General Secretary, Robert Smith.

"It's a possibility," Smith told BBC Radio 5 live. "The board have many powers. They can fine, they can suspend and they can withdraw a licence."

British boxer Dereck Chisora has slapped WBC heavyweight champion Vitali Klitschko at the weigh-in ahead of their world title fight on Saturday.

The two squared up after stepping off the scales at a sports shop in Munich.

Legendary trainer Angelo Dundee has died in Florida, aged 90.

Dundee, famous for working alongside Muhammad Ali for 20 years, is reported to have had a heart attack after being taken to hospital with a blood clot.

The "mystery man" at the centre of the Amir Khan row has told the BBC Sport he was correcting clear errors made by the fight's scoring supervisor.

Mustafa Ameen was accused by Khan of interfering with judges' scorecards in his defeat against Lamont Peterson. But Ameen claims he only pointed out mistakes made by Michael Welsh, who had said he was unwell.

Wednesday's hearing into Amir Khan's controversial December defeat by Lamont Peterson has been cancelled.

Khan's promoters Golden Boy Promotions (GBP) issued a statement saying it was due to "only partial representation of fight officials who were involved". Peterson's camp intend to appeal against last week's World Boxing Association decision to order a rematch of the fight.

But BBC Sport understands talks over a rematch will be held on Wednesday.

Muhammad Ali's talent, charisma and strong principals were responsible for raising boxing's popularity across the world, according to former US president Bill Clinton.

Clinton also credited Ali, who turned 70 on Tuesday, with helping pave the way for Barack Obama to become the country's first black president.

"He made millions of people believe. He was something unique," said Clinton.

The World Boxing Association has confirmed it has ordered a rematch between Amir Khan and Lamont Peterson.

Khan lost his WBA and IBF titles to Peterson in December and has questioned a number of aspects of the fight. And WBA vice-president Gilberto Jesus Mendoza said: "I can confirm we have ordered a direct rematch."

Lamont Peterson's manager and trainer has vowed to fight efforts to overturn his charge's victory over Amir Khan.

Peterson dethroned Khan in Washington DC last month, only for the Briton's camp to launch an appeal, which will be heard on 18 January. Khan is upset the referee deducted him two points for pushing and alleges the scorecards were interfered with.

"We will not let these foul tactics take away from Lamont's hard work and monumental victory," said Barry Hunter.

The International Boxing Federation has confirmed the "mystery man" accused by Amir Khan of interfering with judges' scorecards in his defeat against Lamont Peterson is not an official of the organisation.

The boxing authority said Mustafa Ameen is neither employed nor a sanctioning official, as had been previously claimed by one of the promoters of the fight.

"Mr Ameen does outreach work for the IBF's Sarb [Special Assistance for Retired Boxers] Education Fund," the organisation said in a statement.

US boxer Floyd Mayweather Jr has been jailed for 90 days by a Las Vegas court after pleading guilty to assaulting his ex-girlfriend, Josie Harris, in 2010.

He was also ordered to pay a fine of $2,500 (£1,600) and complete 100 hours of community service. Mayweather, 34, agreed to a plea deal, meaning he will not have to answer felony charges of beating Ms Harris and threatening two of their children.

Britain's Dereck Chisora will face Vitali Klitschko on 18 February after beating David Haye to a fight with the WBC heavyweight champion.

Chisora, 27, will take on the Ukrainian in Munich, Germany. He has twice been scheduled to face Klitschko's brother Wladimir, who pulled out both times through injury.

Miguel Cotto gained revenge for his 2008 defeat by Antonio Margarito by beating the Mexican to retain his WBA light-middleweight title.

Margarito controversially beat the Puerto Rican in 2008, laterreceiving a ban for using illegal hand wraps before a loss to Shane Mosley. On Saturday, Cotto beat Margarito into submission for nine rounds in New York before the fight was stopped.

World heavyweight champion Wladimir Klitschko has called off the defence of his titles against Frenchman Jean-Marc Mormeck on Saturday.

Klitschko, who holds the IBF, IBO, WBO and WBA belts, was taken to hospital on Friday to have a kidney stone removed.

Manny Pacquiao's trainer, Freddie Roach, conceded Juan Manuel Marquez deserves a rematch following their WBO welterweight title fight on Saturday.

Pacquiao won a majority decision in Las Vegas, despite Marquez dominating much of the action in their third fight. "[Marquez] has given us problems three times now," said Roach. "I do think he deserves a rematch first.

Former world heavyweight boxing champion Joe Frazier has died after a brief battle with liver cancer, his family said.

Frazier - also known as Smokin' Joe - had been receiving hospice care in Philadelphia after being diagnosed with cancer several weeks ago. The 67-year-old was the first man to beat Muhammad Ali in 1971, but lost his next two bouts with Ali.

Manny Pacquiao made his fifth pre-fight visit to "Jimmy Kimmel Live," spurring Kimmel to declare himself part of the Pacquiao team: "Each time you've been here, you've won the fight," he says.

On Nov. 12, Pacquiao takes on Mexico's Juan Manuel Marquez.  As The Times' Lance Pugmire reported in May when the contract was signed:

Women's boxing has always divided opinion but now there are splits within the sport over suggestions that competitors should wear skirts.

The latest talking point is not whether women's boxing should become the newest Olympic discipline at London 2012, but what the boxers will actually wear when they compete.

Britain's former WBA heavyweight champion David Haye has announced his retirement from boxing.

Haye, who turned 31 on Thursday, always said he would not fight on past the age of 30. "It has been my intention to retire from boxing on this day ever since I first laced up my gloves as a skinny 10-year-old," Haye said in a statement.

Floyd Mayweather has announced he will end his latest spell in retirement by challenging Victor Ortiz for the WBC welterweight title on 17 September.

Mayweather has not fought since outpointing Shane Mosley in May 2010.
