Tonight, from Las Vegas, Nevada, is the UFC's final event of the 2012 year, UFC 155.
The main card features three middleweight fights and six top competitors.
The co-main event is a lightweight matchup between Jim Miller and Joe Lauzon, and the winner of that could move on to a No. 1 contender fight. Then, in the main event, it's a rematch 13 months in the making, as Junior dos Santos will look to defend his heavyweight title by beating Cain Velasquez for a second time.
Let's take a look at a final breakdown of the main-card odds just hours before the card is set to start.
