Jon Jones has dominated everyone he has faced in the Octagon -- except Alexander Gustafsson.
　　Jones won a decision in their 2013 meeting, but it was a thrilling five-round battle. They fight a rematch on Saturday, Dec. 29, in the main event of UFC 232 at The Forum in Los Angeles.
　　At stake will be be light heavyweight belt that Jones once wore, which will be stripped from Daniel Cormier for inactivity. Jones had the belt taken from him for the second time last year after failing a drug test. This will be his first fight in 17 months.
　　The co-main event is also a title fight -- a superfight, actually, pitting women's featherweight champion Cris Cyborg against bantamweight champ Amanda Nunes.
　　Whose night will it be?
