The Duke of Sussex said the "passion and enjoyment" of sport can bring comfort to people in the "isolated" times we live in.
Harry was speaking ahead of England and Scotland marking rugby's oldest international rivalry when they meet at Twickenham on Saturday.
The game will mark the 150th anniversary of the first ever Test, which took place on March 27, 1871 in Edinburgh.
