Ken Crozier joined the R.U.C. in 1972 at 18years of age. Taking over from the great Tom Turkington at centre half he played along side Gerry Gillespie and of course his brother Alec in an R.U.C. team that had just won the Amateur League in successive years.

He quickly made his first team debut  in October 1973 at Larne against G.E.C. in a Divison 1 Amateur League fixture. At six foot five inches Crozier soon attracted the attention of Linfield whom he joined in 1975 – Ronnie Bell was of course also with the Blues at that time. In a short spell with Linfield he made 22 first team appearances including a European Cup appearance against PSV Eindoven in Holland when the injury depleted Blues lost 8-0.

With the R.U.C. now in the Irish League “B” Division manger Brian Dunlop persuaded him to return to the Police which was the beginning of an outstanding defensive partnership with his great friend and colleague Davy Gardiner. Rejoining the Police team; to whom he had great loyalty; was a tremendous gesture for a player who had the potential to play at the highest level.  In 1978 after an outstanding spell with the R.U.C. during which he played against Glenavon and Glentoran in the Irish cup Crozier decided to immigrate to New Zealand only to return in 1979 when he once again resumed his partnership with Gardiner.

In 1980 he was to be a key member of an R.U.C. squad which really caught the imagination of the Northern Ireland soccer public when they defeated Ards, and Coleraine before loosing in the semi-final of the Irish cup to Crusaders after a replay. Victory would have taken the Police into Europe. At the end of an outstanding season Crozier was to win an Intermediate Cup Final medal and win two Junior International Caps against Scotland and the R.O.I. before once again immigrating to Australia. In 1985 he returned again to the R.U.C. and played  out his career with the Police.
