All eyes will be on Conor McGregor and Dustin Poirier as the lightweight stars bid to settle their thrilling rivalry in a third, and likely final, battle at UFC 264.
McGregor, 32, was handed his first career defeat by knockout on Fight Island in January, with fans and pundits torn as to whether the Irishman has enough to overcome his game American rival.
However, there are plenty of other intriguing battles in Las Vegas this weekend, with two welterweight hopefuls looking to make their case for a shot at Kamaru Usman's title, an intriguing heavyweight affair and a star of the future hitting the octagon. Sportsmail profiles the best of the rest at UFC 264.
All eyes will be on Conor McGregor and Dustin Poirier but some stars will try to steal the show
Gilbert Burns v Stephen Thompson
These two have seen their welterweight championship chance come and go before, but UFC 264 represents a fantastic opportunity to put themselves in the frame for another tilt at the 170-pound title.
Usman has vowed to 'lap' his competition, having swept aside all manner of rivals, including Gilbert Burns, in emphatic fashion.

Thompson, 38, will prove a stern test and is eyeing another title shot in his twilight years
The Brazilian lost to his former team-mate in February and is looking to bounce back against a man who has proved a tricky customer throughout his storied UFC career.
Of all the top welterweights vying for Usman's belt, the champion has yet to face Stephen Thompson. Wonderboy was involved in two gruelling fights with Tyron Woodley, losing out by small margins in both contests, but he remains confident that he can get another shot at the title.
The 38-year-old has won his last two fights and enters UFC 264 with strong momentum. He will need to keep this fight on the feet, though, with Burns' world class jiu jitsu a real threat for the American.
Things are unsettled at the top of the division, with it unclear who Usman will face next. A win and a standout performance could go a long way for either man.
Tai Tuivasa v Greg Hardy
In the middle of Saturday's main card sits an intriguing contest between two heavy hitters.
Tai Tuivasa is on the comeback trail. The charismatic Australian was viewed as a likely contender for the heavyweight title before a three-fight skid saw the 28-year-old take a one-year break from the sport.
Former NFL star Greg Hardy has been on a steep learning curve since changing careers
However, his return to the octagon has seen him register back-to-back wins and he arrives in Las Vegas hoping to add a big name to his list of victims in Greg Hardy.
Hardy has certainly had the attention of the UFC masses since making his debut three years ago. The former NFL defensive linesman has been thrown in the deep end and currently boasts a record of four wins, and three losses.
