Williams' focus moved from tennis to rugby union, which was an amateur sport, in order to pursue a career in
medicine. Williams played club rugby for
Bridgend,
London Welsh and
Tondu. Williams had many high points in his career, being a key player in a Welsh side that won
Grand Slams in 1971, 1976 and 1978, and is particularly remembered for his record against
England. In 10 tests between Wales and England he scored five
tries – exceptional for a full-back – and was never on the losing side. He was also outstanding for the Lions, scoring an important long-range drop goal in the fourth test of the
1971 series against
New Zealand. In the
1974 'invincible' series against
South Africa he again played a major role. Williams chose not to go on the
1977 British Lions tour to New Zealand, after being advised by his consultant to focus on his medical career. Williams retired from international rugby union in 1981 and continued his career as an
orthopaedic surgeon.
Playing style At the times Williams played, the rugby rules restricted kicking to touch. This suited Williams as he did not naturally like kicking and would rather counter attack. For Wales this was helped by playing with very high-quality wingers, such as
Gerald Davies and
J. J. Williams.
