Jon Jones has already put together a long list of great moments in his four-year MMA career, and he will attempt to add to that list at UFC 152, where the light heavyweight champion will try to defend his belt against former titleholder Vitor Belfort.
Should he defeat Belfort, Jones will have matched the great 205-pound title runs of Chuck Liddell and Frank Shamrock with four straight title defenses. The 25-year-old is already being mentioned among the legends of the sport and has even beaten some of them, but a win at UFC 152 would mark one of the bigger moments in his young career.
Still, it is a moment that will be tainted slightly by the fact that Jones will be defending his light heavyweight belt against a middleweight. Although he's a former 205-pound champion, Belfort hasn't competed outside the 185-pound division since his return to the UFC against Rich Franklin in September 2009, and that bout was contested at a 195-pound catchweight.
Here are the best moments in the careers of Jones and the rest of the Top 25 fighters competing in MMA.
