Francis Ngannou has opened up on the tragic death of his 15-month-old son.

The former UFC star sadly lost his son Kobe in April.

Up until now the cause of death had remained unknown but Ngannou has now revealed it was down to a malformation of the brain.

Ngannou said that doctors at the time concluded that Kobe suffered from a swollen lung and that they prescribed medication for that, which lead to him putting his ‘guard down’.

However, shortly after when Ngannou was in Dubai, he was informed of his son’s death via a phone call with his younger brother.

Speaking on the Joe Rogan Experience podcast he said: ‘My phone rang; it was my little brother, saying, ‘Bro, things are not going well here’. He said Kobe passed out. He’s not breathing, we are at the hospital, they kicked me out from the room.’

Ngannou went on to say that as he attempted to find out more information from his brother, a nurse came out and told his younger sibling that Kobe ‘had gone’.

The former UFC heavyweight champion described the impact that his son’s death had on him and admitted it left him with ‘nothing’.

‘In your heart, you feel like you’re broke. You have nothing. Nothing is worth it,’ he explained.

‘I’ve always loved life and know that I have everything but I’m [thinking] like, at least whenever I die, I can go see my kid. I’m going to see him. I’m not afraid of it’.

Back in April, Ngannou’s heartbreaking announcement on Instagram revealed the tragic loss of his son, where he said; ‘Too soon to leave but yet he’s gone. My little boy, my mate, my partner Kobe was full of life and joy. 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 clude (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.’
