Brentford Joining
Brentford at a young age, Gelson progressed through the club's
youth,
'A' and
reserve teams before making his professional debut at age 19 in a 2–0
Third Division defeat to
Halifax Town on 22 August 1961. Despite still being a part-time player, but a loss of form saw him lose it to
Bobby Ross four months later. Gelson was known for his long-range goals and scored three times from behind the halfway line. A "hard man" as a player, in 1970 he ended the career of
Colchester United's
Bobby Howlett in a challenge which resulted in a broken leg for the Us defender. Gelson went on to be a fixture at
centre back until his final appearance for the club in September 1974. He was inducted into the Brentford
Hall of Fame in November 2014 and remained a season ticket holder up until the final seasons at
Griffin Park.
Non-League football After his departure from Brentford, Gelson played on in
non-League football, appearing for
Hillingdon Borough (two spells),
Hounslow and
Walton & Hersham. == Personal life ==
