Byrne was born in Bristol and, after serving in the Irish Guards, joined Bristol Rovers of the Southern League in 1902. The following season he moved to join the Southern League champions, Southampton, as cover for George Clawley. He made his debut in a 2-0 victory over Swindon Town on 23 January 1904, and followed this with a clean sheet in the next match before Clawley's return. He made three further appearances (all victories, with two further clean sheets) before a move to Chelsea in August 1905, for their inaugural season in the Football League.
With Sheffield United's experienced First Division and FA Cup-winner William "Fatty" Foulke also brought in, Byrne acted as back-up, and as with many of Chelsea's debut season reserve players, he made his first team debut in a 7-1 mauling in the FA Cup against Crystal Palace. The tie clashed with a Second Division match against Burnley, for which the first team turned out, and won. Byrne went on to make 3 league appearances that season, before making his final season in the opening match of the 1906-07 season; a 9-2 thrashing of Glossop. With Bob Whiting established himself as first choice goalkeeper thereafter, Byrne signed for Glossop in 1907, where he made eleven Second Division appearances before retiring in 1908.
