It has been erroneously reported by many modern-day sources that he played local football for his hometown club Redcar, but this is not true.
[12] Williamson caught influenza in January 1922,[13] and Harrison came into the team for the visit to Manchester City and kept his place for the rest of the season.
[11] He spent the 1924–25 season with Darlington of the Third Division North as backup to the ever-present James Crumley,[1][14] then signed for another third-tier club, Durham City.
[1] Harrison moved on again in 1926, to Hartlepools United, who had just lost their goalkeeper Billy Cowell to First Division Derby County.
He began the season in the first team, and made 26 appearances in all competitions, the last of which was on 26 January 1929, a 3–1 defeat at home to Southport, but then lost his place to the 20-year-old future England international Harry Holdcroft.
