The other fights from the main event are really promising and all of your mentioned cards are good especially the Umar Nurmagomedov and Muhammad Mokaev fights which will be a banger of a fight.
And Oh! I remember that fight it was really unfortunate for Alistair Overeem to get that gruesome injury his lips were blown open with a scratch from that punch, we can say it was due to the impact that Lewis's punch that made that kind of injury, here is the gruesome image.

Whoa! It was really a gruesome injury he got there I never expected such things to happen in a fight, it was like a slash I thought that it was just bruises and bumps but yeah in boxing they will often get cuts in the forehead but never seen some cuts that are likely on the lip section, it was really unexpected at least for this to see such injury, it just got my hair tingling.
1) What you think about Belal Muhammad achievement and about him in general?
Actually, I don't like the guy and it seems weird that he now has a chance for a title match and I really hate the idea of him being champion, this is just for me I don't know about you guys.
Judging from his face I think he might have lost a lot of betting for Alexander Volkanovski I don't know about you guys but I think that this is the face of misery just on my part what about you guys?

3) FFS, where is
YuginKadoya?

He used to post predictions here on each event. Now is gone; was online, but havent posted since Feb 5.
I don't know why I have scouted the meta section but judging by this thread I think I have solved your question
