FILE - In this May 17, 2008 file photo, former heavyweight boxing champion Mike Tyson poses at the photo call for the film "Tyson" during the 61st International film festival in Cannes, southern France. Mike Tyson has scrapped promotional appearances in London because previous convictions bar him from entering Britain. His publisher said in a statement Tuesday Dec. 10, 2013 that it had been "unaware" of recent changes to U.K. immigration law and for that reason Tyson had to reroute to Paris. Under Britain's immigration rules, anyone sentenced to more than four years in prison is barred from entering the country. (AP Photo/Carlo Allegri, File)
