Watch: Sean O'Malley meets Aljamain Sterling and Merab Dvalishvili at UFC PI, asks them how much they weigh

Sean O'Malley recently ran into Aljamain Sterling and Merab Dvalishvili at the UFC Performance Institute and seemed keen to know how much they weighed.

In a video posted by Dvalishvili on Twitter, the three bantamweights can be seen hanging out in the cafeteria and O'Malley casually asks Sterling how much he weighs.

Sterling nonchalantly replies saying he weighs around 167 lbs and 'Sugar' then redirects the same question towards Dvalishvili, who claims he's at 155 lbs. Notably, 'The Machine' is booked against Petr Yan for a fight in March, while Sterling's rumored fight with Henry Cejudo is yet to be finalized.

Sterling appears to be quite a bit bigger than Dvalishvili and O'Malley. The bantamweight champion pointed out the same, saying:

"I don't know how you guys stay so skinny... I eat one and I'm 170 [lbs]."

Merab Dvalishvili also took a shot at his next opponent in the caption of the video he posted. The Georgian used the hashtag "#petryanhunters", referencing O'Malley's and Sterling's wins over the Russian last year:

"We're getting lunch together @SugaSeanMMA @funkmasterMMA #petryanhunters"

Sean O'Malley defeated Petr Yan at UFC 280 in Abu Dhabi last year, edging out a narrow decision win over the former champion. Now ranked No.1, O'Malley is expected to take on the winner of the rumored Aljamain Sterling vs. Henry Cejudo title fight later this year.

Sean O'Malley on Islam Makhachev vs. Alexander Volkanovski

Sean O'Malley believes that if anyone is capable of getting the better of Islam Makhachev, it would be Alexander Volkanovski.

Makhachev dominantly defeated Charles Oliveira via second-round submission at UFC 280 to win the vacant UFC lightweight title and will be looking to defend his championship for the first time at UFC 284. The Dagestani will take on reigning featherweight champion and pound-for-pound king Volkanovski in Australia next week.

Makhachev is rightfully the betting favorite, considering his size advantage and the stylistic matchup. However, Sean O'Malley believes that Volkanovski is the toughest opponent out there for the lightweight champion. During a recent episode of The BrOMalley Show, 'Sugar' had this to say about the 155-pound title fight:

"What I was trying to say about Alexander Volkanovski, he’s mastered his style. He’s shorter, he’s compact. Is he ggoing to be able to get taken down and held down? You would assume yes, if you watched Islam’s fights... But I think if anyone can do it, it is Alexander Volkanovski. I do think if anyone can beat Islam, it’s me or Alexander Volkanovski..."
