'Everything you go through in life shapes you'published at 05:48 Greenwich Mean Time
Despite Jon Jones' long list of achievements inside the octagon, his support has waned over the years due to his behaviour outside of the cage.
In 2015, Jones pleaded guilty to his part in a hit-and-run which injured a pregnant woman, while last month he reached a pre-adjudication agreement for two misdemeanour charges against him to be dismissed after he allegedly threatened to kill a female anti-doping officer.
Jones served doping bans in 2016 and 2017 although the United States Anti-Doping Agency (Usada) said they were confident he didn't deliberately use performance enhancing drugs.
As Jones was introduced for his news conference with Stipe Miocic, a wave of boos rivalled the cheers.
"I have many regrets but I’m aware that the man I am today has turned out to be a solid human being," said Jones.
"Everything you go through in life shapes you. I wouldn’t have the wisdom I have today if I hadn't gone through some of the things I’ve gone through."
