Career
Callender began his career before the Second World War with local non-league side Crawcrook Albion before moving to Third Division North side Lincoln City. After the war, Callender moved to Gateshead where he made his name. Although playing in the lower divisions of the Football League Callender was considered worthy of a place in the England team by contemporaries.
Indeed such was the esteem in which his play was held that Gateshead turned down a £15,000 offer from Newcastle United for his services.
Wolverhampton Wanderers manager Major Frank Buckley also allegedly made an undisclosed offer for the outstanding centre back. Callender also Captained the Third Division North XI v Third Division South XI. On his retirement Callender managed Gateshead for a short period.
Callender died 25 February 2002.
