Career
He played in The Football League for three clubs, with most of his appearances being made for Chester City. Henderson was 26 before he made his breakthrough into The Football League, when he joined Chester from Witton Albion in December 1978. He had previously spent time on the books of Manchester City without making a first-team appearance and worked as a teacher of physical education in Winsford.
He made his Football League debut for Chester in a 2–1 defeat at Peterborough United on 13 January 1979, with his first goal following four days later against Colchester United.
This goal was unfortunately missed by many travelling Chester fans as their train arrived late. Henderson left Chester at the end of the season for Gillingham, but after an injury hit spell at Priestfield Stadium and a brief loan stint with Crewe Alexandra, he returned to Chester in December 1981.
He left the club at the end of the season, playing his final Football League fixture in a 1–0 loss at home to Carlisle United on 19 May 1982. As well as training as a physiotherapist, Henderson played for non-league sides Telford United, Northwich Victoria, Runcorn, Winsford United and Oswestry Town.
In 1986 he became physiotherapist at Birmingham City, and went on to become part of Lou Macari’s coaching staff at clubs including Stoke City and Celtic.
