[1] Henderson was born in Glasgow in 1932, and started playing football as a youth with his Bishopbriggs-based church team and for Kirkintilloch Boys Club.
[3] He signed for Portsmouth as a 17-year-old, and after completing his National Service in the Royal Army Ordnance Corps[4] he made his debut for the first team against Sunderland in September 1951.
He began the following season still at Molineux and appeared in a handful of early games in what would be another championship-winning campaign, but played only nine matches in all for Wolves.
[7] Swindin's tinkering with the Arsenal attacking line-up meant the versatile Henderson was unable to hold down any particular position in the side, and midway through the 1961–62 season he was transferred to Fulham for £14,000.
[7] In his first season at Craven Cottage, Henderson helped Fulham reach the 1961–62 FA Cup semi-final, in which they lost narrowly to Burnley.
[10] Henderson's only goal for Scotland came on 3 October, in a 3–1 win over Northern Ireland in a 1953–54 British Home Championship that doubled as a qualifying group for the 1954 World Cup.
