'Johnny' King caught City's attention when playing in Peterborough schools football and the Foxes promptly snapped him up on a part-time basis during the war, where he went on to make 40 appearances.

His stay at the club lasted well beyond the war, however, with a stint of over a decade seeing him rack up over 250 appearances in total, playing at left-half and occasionally as inside-forward.

He continued his work as a farmer during his playing days with the club and unfortunately missed the entire 1954 championship campaign through injury before playing one match in the top flight and moving on to Kettering, where he finished his career.
