Mike Tyson has taken to Twitter to pay homage to late boxing legend Smokin' Joe Frazier, who died at 67 Monday in Philadelphia after a battle with liver cancer.

"Today is a sad yet remarkable day as we mourn the death of boxing legend Joe Frazier & honor him by celebrating his amazing accomplishments," Tyson, 45, tweeted, expanding in detail about his admiration for the fallen fighter.

"Frazier and [Muhammad] Ali were quintessential the apex of pedigree fighting in which each man would not give an inch until they were dead. Their era was competitive fighting at the highest level. As a young fighter it has always been an honor to be compared to [Frazier]."

Boxing legend Smokin' Joe Frazier died Monday night in his hometown of Philadelphia after a battle with liver cancer. He was 67.

Frazier will be best remembered for becoming the first boxer to defeat Muhammad Ali, downing The Greatest of All-Time in the Fight of the Century, a March 1971 bout at New York's famed Madison Square Garden. He later called the win "the greatest thing that ever happened in my life."

The pair would go on to have three matches overall, two in the Big Apple and once in the Philippines, famously dubbed “The Thrilla in Manila.”

Joe Frazier is in the fight of his life.  The legendary boxer of 'Thrilla in Manilla' fame was diagnosed with liver cancer a month ago. He is now under hospice care.

"We're looking for some miracles," Leslie Wolff, Frazier's business manager, told The Philadelphia Inquirer.

"When you're dealing with the Big C, it's not an easy thing to deal with."

Frazier's career lasted 20 years and featured three of the most famous bouts in boxing history, all against Muhammad Ali.

Their first fight, in 1971, took place at Madison Square Garden and the closed circuit viewing audience was estimated at an astounding 300 million worldwide.

It was one of the greatest scandals in Olympic history and now Tonya Harding and Nancy Kerrigan are being offered big bucks to settle their grudge -- not on the ice, but in the ring!

It has been almost 20 years since Harding’s ex-husband and bodyguard hired a man to attack skating rival Kerrigan, smashing her leg with a baton in an attempt to prevent her skating in the 1994 Olympics.

The attack failed to cause long-term damage and Kerrigan went on to win an Olympic silver medal, while Harding was charged with covering up the assault.

They have not even entered the ring yet and already Tareq Salahi and Jose Canseco already looked like they were about to come to blows on Thursday as they met to promote their upcoming fight, and RadarOnline.com has video of the stand-off.

The notorious White House gatecrasher and shamed former baseball player will be gloving up and coming to blows in the upcoming Celebrity Fight Night boxing competition on November 5 to raise money for several children's charities.

When the infamous pair met on Thursday, Salahi began the unusual news conference by holding up his iPhone and showing the audience a photo.

"After I found this picture of Jose and my wife taken about five years ago, I am ready to take this man down. I had no idea that my wife has been lying to me every single day of our lives," he said.

Four people were arrested on Friday after they were caught breaking into the home of world champion boxer Manny Pacquiao.

The boxer was training for a fight in his native Philippines when detectives from the Los Angeles Country Sheriff's Department, who happened to be driving by, saw the crime in progress.

A security guard on duty at the house was on his lunch break when the incident occurred.

"Manny is happy that nothing was stolen," said the boxer's attorney Franklin Gacal.

Manny, who is also a singer and popular personality for commercial endorsements, is set to return to the U.S to fight Juan Manuel Marquez of Mexico.  That fight will take place November 12 in Las Vegas.
