UFC opens its 2015 campaign with arguably one of its biggest championship fights in history as UFC 182 sees the highly anticipated 205-pound title collision between Jon Jones (20-1 MMA, 14-1 UFC) and Daniel Cormier (15-0 MMA, 4-0 UFC) finally take place.

Tension between “Bones” and “DC” has built over the months from their infamous September brawl to several heated interviews. The rivalry will come to a boiling point Saturday night at Las Vegas’ MGM Grand Garden Arena when the two sides meet for Jones’ belt.

The title fight is far more than just a grudge match, though. Jones and Cormier own two of the most impressive resumes in MMA, as in a combined 36 professional fights, neither has suffered a knockout, submission or decision loss, a feat that’s only happened twice before in UFC title fight history.

To dig into some of the milestones the UFC 182 fighters have already accomplished or are on the verge of accomplishing, here are 50 pre-fight facts about this UFC’s 2015 debut.

Main event

Jones owns or is on the verge of owning several light heavyweight and overall UFC records, all of which can be viewed on his complete UFC career stat sheet.

Jones (84.5-inch reach) will have a 12-inch advantage over Cormier (72.5 inches), the third largest differential ever in a UFC fight.

Jones and Cormier will mark the first fight in history when two fighters on at least a 10-fight UFC/Strikeforce/WEC/PRIDE winning streak will meet in MMA competition.

Cormier is 5-0 in his career against fighters who once held or challenged for a UFC championship.

Cormier has never been taken down in his MMA career.

Cormier holds the record for the most victories (eight), knockouts (four) and significant strikes landed (305) in the history of the now-defunct Strikeforce heavyweight division.

Cormier has out-landed every UFC and Strikeforce opponent he’s faced. He out-lands his opponents by a more than 3-1 ratio; landing 506 significant strikes to just 161 absorbed. His UFC/Strikeforce strike differential of +2.78 per minute is the third highest among fighters at 205 pounds or higher in the combined history of the two organizations.

Cormier’s submission of Dan Henderson at 3:53 of round 3 at UFC 173 stands as the second latest submission in a three-round UFC light heavyweight fight. Forrest Griffin holds the record with his finish of Mauricio Rua at 4:45 of round 3 at UFC 76.
