The fighter stunned onlookers on Saturday (29Sep12) when he was seen sporting a neck brace at a Las Vegas charity auction held by the World Boxing Council and Hublot Watches.
He went under the knife to have titanium pins inserted to support his neck as a result of an old spinal injury, which had been causing him pain.
A representative insists Tyson is enjoying a speedy recovery, telling TMZ.com, "It's a very common surgery, especially for athletes. He feels great... just has to wear the neck brace to keep everything stable for the next three weeks."
Officials at the New Zealand Immigration Service have reversed their decision to grant Tyson entry into the country, where he had hoped to stage his one-man show for charity next month (Nov12).
The decision came after a benefactor at New Zealand's Life Education Trust charity withdrew a letter of support for Tyson.
Associate Immigration Minister Kate Wilkinson explains, "Yesterday evening the Life Education Trust contacted my office and asked for that letter to be withdrawn, making it clear that the Trust no longer wants to have any involvement with Mr. Tyson's visit.
"Given that the Trust is no longer supporting the event, on balance, I have made the decision to cancel his visa to enter New Zealand."
Max Markson, the promoter for Tyson's planned one-off performance in Auckland, is wading into the controversy to help The Hangover star secure clearance, insisting authorities should overlook his 1992 rape conviction.
He tells the New Zealand Herald, "It would be a tragedy if Mike Tyson could not come to New Zealand to do his show. We'll see if we can get a visa issued again... He's a vegan, he's sober, he's a great role model about how man can turn his life around and I'm sure there's worse people walking the streets in New Zealand today than Mike Tyson will be in the 20 hours he is here, hopefully, with his wife, his children."
The fighter, 46, stunned onlookers on Saturday (29Sep12) when he showed up to a charity auction held by the World Boxing Council and Hublot Watches in Las Vegas with a large scar on his neck.
It has since emerged that Tyson recently went under the knife and had titanium pins inserted to support his neck as a result of an old spinal injury which had been causing him pain.
The sports legend took to his Twitter.com page on Sunday (30Sep12) to offer up an explanation, writing: "I was damaged before I even entered boxing."
The fighter has already tried his hand at acting in Crocodile Dundee in Los Angeles, The Hangover and its sequel The Hangover II, and now he's set to star in the latest installment of the horror parody franchise.
He was spotted on set in Atlanta, Georgia on Thursday (27Sep12) with co-star Heather Locklear.
Charlie Sheen and Lindsay Lohan play lovers in the film, while Ashley Tisdale and Molly Shannon also star.
Tyson, who has been wowing theatre critics in New York with his one-man show, is hoping to take the concept of his Broadway hit to the other side of the world in November (12) - but officials at the New Zealand Immigration Service have yet to agree to give him the visa necessary - because of his 1992 rape conviction.
Under New Zealand law, anyone convicted of an offence which carries a prison sentence of five years or longer will not be granted a visa unless there are exceptional circumstances.
Tyson, who sports a Maori tattoo design on his face, hopes the officials will see sense and allow him to enter the country.
In a video interview with local reporters on Thursday (30Aug12), the boxer said, "I'm not going to sit here and cower and beg to come to your country. If I can't come, I can't come. It will be my misfortune but I don't want to feel like I'm on trial to come to your country.
"I've never been to New Zealand. I've never had the opportunity before. It must be a serious country if I can't go there."
Tyson's promoter, Max Markson, adds, "He's a great ambassador and he really does have a tremendous story which he has to tell to the people of New Zealand and it would be a tragedy if the show that he's been doing on Broadway for the last few weeks can't be told."
The boxing legend is currently battling with officials in New Zealand over plans to launch a series of self-help lectures there later this year (12) and it has now been revealed he is also facing a struggle to get into Australia over his 1992 rape conviction.
Tyson hopes to attend a motivational conference in Brisbane, entitled Mike Tyson's Day of the Champions, on 16 November (12) but he is facing a challenge from authorities, according to News.com.au.
Officials in Australia often reject visa applicants because of past criminal records, but Tyson hopes immigration officers will see he has put his problems behind him.
He says, "You shouldn't be worried about me. I'm coming over there with my family - I don't want to be on trial for my life to come over there."
Tyson's Australian agent, Max Markson, adds, "Mike was sentenced to six years (for rape), he served three and was released on good behaviour. It was 20 years ago. I think Australia welcomes people, we have a history of welcoming people. We forgive."
Marvin Mitchelson allegedly drew up divorce papers for Givens in the midst of her legal battle with the retired boxer in 1988, and now the lawyer's widow, Marcella, has accused the 47 year old of failing to pay him for his work.
She tells the New York Daily News, "Marvin worked really hard on getting those papers filed overnight for Givens and was very upset she fired him and never paid him the $15,000 (£9,375). (I) could certainly use the money."
However, Givens' publicist, James Grant, has dismissed the claims, saying, "She had one meeting with Mitchelson and signed immediately with Raoul Felder, who represented her throughout the entire case. It was just a brief meeting. She doesn't owe him any money."
Mitchelson, who represented dozens of celebrities throughout his career, including Robert De Niro and Sylvester Stallone, lost his battle with cancer in 2004.
Tyson and Givens married in February, 1988, but split several months later.
Retired boxer Mike Tyson has scrapped an upcoming fan meet-and-greet in New York due to "circumstances out of my control". Ticketholders to the Memorabilia event in White Plains on Sunday (19Aug12) have been invited to attend another date at the Big Apple's Hofstra University on 21 October (12) instead.
If there was anything to take away from the 2011 box office hit The Hangover Part ll (aside from the realization that a lot more Chow requires a lot more patience as a viewer) it's that writer/director Todd Phillips' hangovers must have a lot of déjà vu. In addition to Ken Jeong's Chow, the sequel to the wildly successful, infinitely quotable original, featured plenty of elements from The Hangover, including lost wolf pack members and a cameo from Mike Tyson.
So it's of no surprise that Phillips is taking another key element from the 2009 Hangover and infusing it into the upcoming third installment. Hollywood.com can confirm that Heather Graham, who played Jade, the sweet Las Vegas stripper/escort who marries Ed Helms' kindly, anxious Stu when he's in a drunken stupor, will appear in The Hangover Part lll. Graham, whose charming, funny turn as Jade made her one of the highlights of the original, will reprise her role as Stu's estranged wife and Carlos/Tyler's mom. (One can only hope that Carlos/Tyler also makes a return, though they should probably keep him away from Zach Galifianakis' Alan and/or any doors.) While The Hangover Part ll was an undeniable smash (the movie became the highest-grossing R-rated comedy of all-time with a staggering $488 million worldwide intake) many critics and fans were disappointed with how much the sequel recycled from the first film. So does the news of Graham mean more of the same for the third flick? Or will her appearance simply mean some fun that was missing from the second flick? One can only guess that the re-emergence of Jade will throw in some surprises for Helms' now-married Stu (maybe there's been a little sibling for Carlos/Tyler along the way), who can never seem to catch a break in these movies. Better yet, maybe it will take them back to where it all started: Vegas. (Though rumors and reports have placed the third movie everywhere from Tijuana to Los Angeles to an insane asylum. Either way, it will be nice to have a female presence in The Hangover Part III, something that was sorely missing from the second. The 42-year-old who last seen in 2011's far more family-friendly Judy Moody and the Not Bummer Summer, will also be seen in the porn drama About Cherry alongside James Franco. The Hangover Part III is anticipated to have a May 2013 release from Warner Bros. Are you excited that Heather Graham, who was indisputably one of the best surprises and highlights of The Hangover, is returning? Or are you afraid that, like the second, the third will simply rehash too much from the original? Are you hoping that Stu and Jade will finally wind up together? (Seriously, who didn't want to see that?) Share in the comments section below. [Photo credit: Warner Bros.] More:
