In the buildup to the UFC 189 fight against Mendes, McGregor tells the story of Brendan Malone, a young fan, who died of cancer.
I got a phone call from a person at the UFC, saying the Make a Wish Foundation has reached out to them, and this kid has cancer or leukemia. And this is going to be his last wish, and his last wish is going to be to talk on the phone to you, and I didn’t know what the…so I rang the kid and we talked for a long, long time. I talked with his friends in the hospital and his family. And today, or last night, he passed away. It f-cked my head up because this little kid is in Ireland, and I’m telling the kid ‘I’m gonna take this belt, and I’ll bring the belt to you’, and I was saying we’re going to raise the belt up together.
