The day is finally here and the moments of anticipation are over as tonight we will see UFC light heavyweight champion Jon "Bones" Jones' first title defense against Quinton "Rampage" Jackson.
Fight fans will find out if Jones is the next elite fighter in the UFC and can go on a run of successful title defenses.
When he captured the title, Jones dominated an elite fighter in Mauricio "Shogun" Rua and is looking to do the same to the former champion.
In Jackson's last fight, he put up a forgettable performance against Matt Hamill, a fighter Rampage should have dominated, but could not finish.
Rampage is known for the power he packs in his punches, but has not been able to finish a fight since 2008 when he knocked out Wanderlei Silva. A lot of people have questioned whether or not his focus is not entirely on the fight game as he has a budding acting career.
He will look to make a return to his popular self against Jones in what should be a great fight.
Jones and Rampage is not the only exciting thing on a card that is full of intriguing matchups between fighters young and old.
Fans will get to see the debut of the latest Ultimate Fighter winner Tony Ferguson as he battles UFC veteran Aaron Riley.
Travis Browne will look for yet another impressive performance after his incredible knockout victory against Stefan Struve opened up a lot of fans' eyes to the Hawaiian's skills.
This may also be the final time we see UFC legend Matt Hughes in the octagon as his contract is up after his fight with Josh Koscheck. The wrestler has been considering retirement for some time now.
So let's take a look at some of the biggest questions being asked about fight night.
