In his role as a football referee, Prince-Cox took charge of 32 international matches in 15 countries. Part of his role at the Royal Meteorological Society was to deliver news of the weather to the King at Buckingham Palace.
Prince-Cox became the sixth manager of Bristol Rovers on 1930-10-23, and remained in the job for almost six years, until 1936-10-10. He introduced the blue-and-white quartered shirts in which the team now play in an effort to make the players look larger and more intimidating. He also gave the club the nickname The Pirates, which is used to this day.
