Former heavyweight champion Mike Tyson's return to the boxing ring has been delayed until 28 November. The 54-year-old will face former four-weight world champion Roy Jones Jr in an exhibition bout in Los Angeles. The bout was scheduled to take place on 12 September but will now be on the United States' Thanksgiving weekend. "Changing the date will give more people the opportunity to see the biggest comeback in boxing history," Tyson said. Tyson last fought professionally in 2005.
