Former UFC heavyweight champion Francis Ngannou is mourning the loss of his young son, Kobe.

The cause of death has not been revealed. Kobe died Saturday.

“Too soon to leave but yet he’s gone. My little boy, my mate, my partner Kobe was full of life and joy,” Ngannou posted on Monday on “X,” the social media platform formerly known as Twitter. “Now, he’s laying without life. I shouted his name over and over but he’s not responding.

“I was my best self next to him and now I have no clue of who I am. Life is so unfair to hit us where it hurts the most.

“How do you deal with such a thing? How can you live with it? Please help me if you have an idea because I really don’t know what to do and how to deal with this.”

Ngannou continued to mourn on Monday.

“What’s the purpose of life if what we’re fighting tooth and nail to get away from is what finally hit us the hardest!?” he wrote in a separate post on X. “Why is life so unfair and merciless? Why does life always take what we don’t have? I’m f–king tired.”

Others in the MMA community reacted to the news.

“I am so sorry to hear of your loss Francis, my prayers are with you and your family at this time,” former UFC champion Conor McGregor posted.

Former UFC women’s featherweight champion Cris Cyborg offered a prayer.
