Everyone in the UFC world tuned in to the weigh-in for Khabib Nurmagomedov vs Justin Gaethje on Friday morning, and it seemed like everyone left with the same reaction.

Khabib did not look right.

The Russian champion could barely stand on the scales without support, and then cut a hugely relieved figure when his weight was announced.

It was very evidently clear that the lightweight champion has had a tough camp and has clearly struggled to make the 155lb weight.

The assistance to get on the scales, the frail look and then the fact he was hugely relieved when it was announced tells its own story.

Fans in the aftermath were quick to say he's struggled to make weight, while others put it down to him still mourning the loss of his father, who passed away earlier this year.

Whether that's accurate or not remains to be seen, but according to fresh reports, as per The Sun, Khabib did put his body through A LOT over the last few days.

The report sites Russian outlet TASS, who claim Khabib had to cut one stone and five pounds in order to get down to the correct weight.

That is a huge cut to make over the last few days and that could possibly explain why he looked so out of it on the scales during the weigh-in.

Khabib is still going into the fight as favourite tonight in Abu Dhabi on Fight Island, but after seeing his appearance on Friday, some people may not feel so confident now.

Gaethje will be confident, however, that he can defeat The Eagle just like he did Tony Ferguson earlier in the year.

However, we can't take Friday's incident as concrete evidence; maybe Khabib will be feeling a lot better come fight time.

One thing is for sure, it's going to be epic!
