Wales Rugby League chairman Brian Juliff said: “Glyn was a good friend and teammate to me at both Wales and Wigan.
“He was a great character, an outstanding athlete and fearless competitor who was respected and admired throughout rugby league and rugby union.
“We will all miss Glyn’s presence, sense of humour and infectious personality. Condolences to all of Glyn’s family and RIP to a top man.”
