Hamilton, Lanarkshire born inside left George Gibson began his football career with Kirkintilloch Rob Roy from where he joined Scottish League club Dundee, in 1922, scoring once in 5 matches for The Dark Blues and after a loan spell with St Johnstone in 1923 where he scored twice in 9 appearances, he joined hometown club Hamilton Academical in 1924, signed to replace the injured Tom McCrorie. The longer he played with The Accies the better he became and it was no surprise to find that in early 1927 English clubs were watching his progress.
A hat trick in a Scottish Cup tie at Stranraer did his reputation no harm and when Rangers put Hamilton out of the Scottish Cup on 19th February that was almost the end of his time with Accies, one more match was played against Hibernian at Easter Road the following week before, on 5th March 1927 after 20 goals in 80 appearances, Bolton Wanderers secured his signature despite the attentions of Everton who were also keen to land him. He went straight into the side for his Football League debut against West Bromwich Albion, scoring a hat-trick the following month in a 5-0 win over Everton.
In 1928-29 he scored 20 goals for The Trotters and was only behind Harold Blackmore in the goalscoring list, a total including 3 in Bolton’s Cup run that saw them win the 1929 FA Cup Final at Wembley when they beat Portsmouth 2-0, so completing a hat-trick of FA Cup wins for Wanderers in the 1920’s. However with Bolton struggling and facing what would be relegation, he joined Chelsea in February 1933 following an excellent display against Chelsea in the FA Cup, having scored 81 goals in 255 appearances for The Trotters. A regular for The Pensioners for his first four seasons at Stamford Bridge, he became a fringe player from April 1937 onwards, by the time he retired in May 1939 he had scored a further 24 goals in 142 appearances for Chelsea, scoring more than 100 goals in nearly 400 matches in the English Leagues, only ever playing in the English top flight.
