He signed for Southampton in April 1914, and made his debut at right-back in a 2–1 defeat at Northampton on 18 April, the penultimate match of the 1913–14 season, filling in for the injured Fred Smith.[2] Following Smith's retirement in the summer of 1914, Green became the established right-back, playing in the first twelve matches of the 1914–15 season, before losing his place to Jack Small in November, although he returned to the side in March.[3]
Described as "an outstanding full-back, neat in style and quick off the mark",[1] Green was expected to go far in the game, but his career was interrupted by the outbreak of World War I, bringing the end of normal football in 1915. The "Saints" retained his registration during the war and he returned to the club in 1918, making a few appearances in the wartime leagues.[1]
In 1919, Green decided to return to Kent and Southampton agreed to release him. He re-signed for Northfleet United and helped them win the Kent League title in 1919–20.
