Career
Swansea born Deacon began his career with Morriston before switching to Swansea in 1890. The next season he was selected to represent the Wales national team against Ireland in the 1891 Home Nations Championship. Deacon was one of four new Welsh players brought into the pack for the match, including Swansea team-mates David and John Samuel, following losses in the first two matches of the tournament against England and Scotland.
Deacon was reslected to play in all three matches of the 1892 Championship, now under the captaincy of Newport legend Arthur "Monkey" Gould.
