Pics: These images of Conor McGregor with Super Gav before he passed away will melt your heart
The father of super hero Gavin Glynn, who passed away in 2014 following a battle with a rare form of cancer, has shared poignant images of his son with Conor McGregor ahead of tonight's UFC 196.
John Glynn shared four images on social media of McGregor, who goes head to head with Nate Diaz in the early hours of tomorrow morning in Las Vegas, playfully grappling with Gav, who is wearing his trademark Superman costume.
Four-year-old Gavin captured the heart of the nation as he bravely battled against a rare form of cancer, Rhabdomyosarcoma.
The Co Wicklow youngster first came to public attention in early 2014 after his dedicated family reached a €350,000 fundraising target in just one week to pay for treatment for him in America.
However, he sadly passed away in his family's home in October 2014 surrounded by his parents John and Jayne and siblings Conor and Lucy.
