Conor McGregor, former UFC champion in two weight classes, has given his support to Francis Ngannou, the promotion's former heavyweight champion, who lost his 18-month-old son yesterday.

"I am very saddened to hear of your loss, Francis. My prayers are with you and your family at this time," Conor wrote on social media.

News of his son's death broke yesterday. Later Francis wrote a post in which he shared his grief and told how hard it is for him now.
