The UFC returns tonight with a mouthwatering clash for the interim lightweight title as Tony Ferguson takes on Justin Gaethje in Florida.
With 155lb champion Khabib Nurmagomedov unable to fight, Ferguson and Gaethje will square off for the right to take on the Russian later this year.
And although Ferguson is the favourite to have his hands raised, there are plenty of people who believe Gaethje can spring a surprise.
There could also be a shock on the cards in the co-main event as Dominick Cruz returns from a 40-month absence to challenge Henry Cejudo for the bantamweight title.
Cruz was the long reigning champion until he lost to Cody Garbrandt in 2016 and was then sidelined through injujry.
