John Jeffrey (born 25 March 1959 in Kelso in the Scottish Borders) is a Scottish former international rugby union player. His nicknames are "The Great White Shark" and "JJ", the former widely thought to be because of his blonde "thatch of hair", though in a recent book called 'The Grudge' by Tom English, it is a nickname that was given to him because of his very white skin.
Richard Bath has described him as "one of the most galvanising sights in Five Nations rugby throughout the 1980s and early 1990s."
Jeffrey was educated at St Mary's School in Melrose and Merchiston Castle School. He won forty caps for Scotland between 1984 and 1991, making him, at the time, Scotland's most capped flanker. He was also a British and Irish Lion with Scotland team mate Finlay Calder in 1989.
Jeffrey's "day job" was his Borders farm, of which he had only one regret: "If I stand on a hill I can see England."
Invariably first to the breakdown point, first with the tackle, or first with an inspired counter, Jeffrey had the ability to score important tries, of which he scored 11, another Scottish record at the time, shared with back-row colleague Derek White. He was also a member of the British Lions on the tour to Australia in 1989.
He was an outstanding performer in the Grand Slam season of 1990 (he was the one who started the move from the scrum that led to Gavin Hastings's famous kick to Tony Stanger, sealing the victory against the English), Jeffrey had been a British Lion on the 1989 Tour of Australia, ironically being kept out of the Test side by his national team-mates Finlay Calder and Derek White, and Englishmen Mike Teague who would suffer for this indignity in the famous Calcutta Cup showdown a year later.
