A tough tackling defender, who made a handful of first team appearances, before going on to have a long career in the lower divisions.
Came through the Spurs youth system and was a member of the side that won the 1990 FA Youth Cup. It was Peter Shreeves who was the youth team manager who moved Hendon from centre-half and right back to midfield, where his ability brought him representative honours, becoming the England Youth captain.
Found few opportunities in the first team at Spurs, with his time ending with a hasty challenge in a Makita Cup match with Chelsea at the Lane, which did not go down well with the management.
Having spent loan spells with Portsmouth, Barnsley and Leyton Orient, he subsequently moved to Brisbane Road on a permanent basis, staying for three years with a brief loan to Birmingham City while there. Moving on to Notts County, Ian was part of the Third Division Championship winning team in 1998 and having spent subsequent time at Sheffield Wednesday, Barnet on loan and Peterborough United, Hendon moved to Barnet, when they were in the Conference and as captain he took a vital role in gaining promotion as champions with a talented group of young players.
In 2009, he stopped playing, but took on some scouting and coaching duties, eventually being appointed to the post of assistant manager at Barnet, alongside Paul Fairclough and was joint manager with fellow ex-Spur Danny Maddix until Martin Allen came in as full time manager. When Paul Fairclough left as the Bees boss in 2011, Hendon took over the hot seat and was given a two year deal in 2009, but failed to see the end of the deal, as he was sacked on 28th April 2010. WIthin a month he had been appointed as manager of Dover Athletic, but left after just 18 days to become Andy Hessanthaler's assistant at Gillingham.
West Ham United took him to Upton Park in July 2011 as development coach, promoting him to First team coach in December 2012.
