Morgan won 29 caps for his country between 1951 and 1958, and also captained the Lions on the 1955 tour of South Africa.
On that tour he earned spectacular praise from all quarters after inspirational performances in two victories, with the South African media dubbing him "Morgan the Magnificent".
After retiring from the game in 1958 he joined the BBC, commentating not just on rugby but on everything from the Olympics to royal weddings - as well as being one of the original captains on A Question of Sport.
The undisputed highlight of his commentary career, however, was the famous Barbarians v All Blacks match in 1973, in which Gareth Edwards scored what is widely regarded as the greatest try of all time.
Morgan admitted that covering the match had been "one of the great privileges of my life", and that he felt lucky to be in the hot seat after Bill McLaren had not been able to work that day.
"The game had everything," he told the Independent in 2003.
"It had all the qualities of an exhibition game, yet great toughness and both sides wanted to win.
"I was thrilled to be able to convey something of the atmosphere to a live audience in New Zealand, as well as Great Britain."
