VIDEO: McGregor heartbroken by death of young fan

"It's just a really sad situation and it's heart-breaking. I've lost family members to cancer and it is a horrible, horrible thing."

Conor McGregor’s whole image is built on his boundless self-confidence and quick wit, so it is a measure of how upset he was that he stumbled his way through a television interview last night.

The UFC star had been told about the tragic death of Brendan McGlone, a 14-year-old from Tyrone who passed away earlier this week after a battle with cancer.
