First capped against Australia in 1947 he went on to win 16 caps for Ireland and was a vital member of the famous 1948 Grand Slam team.
He toured with the British & Irish Lions to New Zealand and Australia in 1950, scoring two tries in a Test match against the Wallabies.
The committee and staff of the IRFU offer their sincere condolences to his family at this sad time.
Jimmy Nelson OBE, 1921-2014. May he rest in peace.
