It seems the UFC 279 fight card is getting a big shake-up.

*This is a developing story and will be updated shortly.*

Las Vegas, NV — Khamzat Chimaev weighs in at 178.5 pounds for his welterweight fight with Nate Diaz and shrugs and said, “not that bad” and walks off the scale.

There’s no word yet if the fight will go on.

The UFC weigh-in broadcast revealed that Chimaev was having difficulty making weight, piquing the interest and suspicions of the media and fans alike.

Then Ariel Helwani revealed the main event welterweight was still eight to 10 pounds over the limit.

Shortly after making weight, Holland tweeted “professionals make weight” and included a middle finger emoji.

Chimaev’s opponent, Nate Diaz stepped on the scales at 171 pounds for their bout. Watch him weigh in here.

Yesterdasy a backstage squabble happened that involved four fighters and more than 100 people, according to UFC president Dana White who spoke to the media shortly after canceling the press conference altogether on Thursday.

It seems that the fallout of that brawl, which started when Chimaev and Holland began arguing and then escalated from there, could be affecting the fight.
