We are heartbroken to learn of the tragic death of ICW World Heavyweight Champion, Adrian ‘Lionheart’ McCallum. Adrian was a mainstay of ICW and British professional wrestling. Most importantly, he was our friend. His passing leaves a huge hole in the lives of those who knew him. pic.twitter.com/qmjnZTb5Lb
