The UFC’s annual Super Bowl weekend extravaganza once against touches down in “Sin City” as UFC 183 is set to take place at Las Vegas’ MGM Grand Garden Arena.

The event features one of the most anticipated headliners in recent history as former longtime UFC champion Anderson Silva (33-6 MMA, 16-2 UFC) returns to the octagon from a broken leg 13 months ago to take on former Strikeforce champ Nick Diaz (26-9 MMA, 7-6 UFC).

The contest marks Silva’s first non-title bout in the middleweight division since he made his UFC debut in 2006. With two consecutive losses to his name, an argument could be made the matchup with Diaz is the most significant “The Spider” has had to date.

Diaz is hardly coming into the contest fresh, though. The 31-year-old announced his retirement from competition following a UFC 158 loss to Georges St-Pierre, but now he’s back to take on another one of the sport’s all-time greats.

Although all eyes are on the main event, Saturday’s showcase is far from a one-fight card. Several meaningful bouts between ranked contenders are set to take place, and for the numbers behind all those fights as well as the headliner, check out 80 pre-fight facts about UFC 183.
