UFC fans are worried Israel Adesanya will be drastically undersized for his light-heavyweight showdown with Jan Blachowicz.
The Last Stylebender will challenge the Pole for the 205lb strap early on Sunday morning in the main event of UFC 259 in Las Vegas.
Reigning middleweight king Adesanya has opted against putting on a considerable amount of size for his light-heavyweight bow, a decision which has concerned some fight fans.
After the Nigerian-born Kiwi shared a photo of himself walking past Blachowicz during the UFC 253 fight week, one fan tweeted: "U too skinny bro."
Another said: "You’ve got no muscles bro, ur gnna get knocked out.
"I love ur fights and watching u win but it seems a bit too big and powerful for u."
Another of Adesanya's followers taunted his frame by saying: "Jan looks bigger than skinny Boy."
Blachowicz was then tipped to add Adesanya's name to his victim list by another fan, who said: "U gonna get WHACKED boi!"

Another chimed in and said: "Skinny for 185… too skinny for 205."
One fight fan was concerned about Adesanya's power at light-heavyweight, asking: "He looks bigger but can he hit faster and harder?"
Adesanya, 31, is expecting to give up a considerable amount of weight to Blachowicz and reckons he'll tip the scales at 193lbs.
He told ESPN: "My body knows it’s fight week already, so it’s gonna start dropping weight because this is what my body does.
"My body just realizes, ‘Oh, yeah. This is what we’re doing’.

"So, I’m just gonna keep the same energy. I’m not gonna change anything different and then start to like get all crazy, and, yeah.
"Don’t be surprised if I weigh in at like 193. Yeah, don’t be surprised.”
He added: “Put it this way: I can still make 185 if I have to. Same flex, baby. Yeah, same thing.
"Yeah, there’s nothing, it’s just silly to me when people decide to go ‘add more muscles’ to their frame that they’re not used to over the years they’ve been working this game.
"So, yeah, I don’t know. For me, I just do this thing different. I wanna bring it back to the rawness of martial arts, technique.
"So don’t worry about weight. Don’t worry about all that.”
