Jock Millar had played for a string of clubs in Scotland, England and Ireland before signing for Exeter City from Benburb in 1938. Scoring three times in nine games he left for Astley Bridge in Lancashire before retiring.

Commencing his career with Saltcoats Victoria, Jock played for Bridgeton Waverley and Kilmarnock before signing for Barnsley in 1928 where he netted five goals in 17 league appearances. Staying for a season, he moved on to Hartlepool United, for whom he scored five times from 18 league starts. After that he moved between Workington, Lancaster, Glentoran and back to Lancaster before signing for New Brighton in 1937 where he featured in one game. 

Jock moved to Rochdale later in 1937, where he featured in 26 league games (8 goals), ahead of returning to Scotland to play for Benburb from where he joined Exeter City in the summer of 1938. Making his debut for the Grecians in a heavy defeat at Queen’s Park Rangers in September 1938, he retained his place to feature in the next eight matches during which time he scored against Ipswich, Brighton and Torquay. 

Not featuring after the Torquay game on 15 October, Jock didn’t feature again for City and returned to Lancashire once again to turn out for Astley Bridge and Hyde United.
