He is a former chairman of the Professional Footballers' Association (PFA) and holds a UEFA A Licence coaching qualification.

[2] He was introduced to football from an early age, his grandfather, Ernest Humphreys, played for Millwall, Motherwell and St Mirren.

[4] In 1995, after leaving Newfield Secondary School, Humphreys became part of Sheffield Wednesday's youth squad.

[4][6] Humphreys' pre-season form earned him a full league debut in Wednesday's opening match against Aston Villa.

[8][9] Humphreys was seen as the driving force behind Sheffield Wednesday's shock early lead at the top of The Premiership.

[18] Humphreys impressed on trial, scoring 3 goals in 7 appearances, and it looked likely that Cambridge manager Roy McFarland was going to offer him a contract.

[19] After the sacking of Roy McFarland, new Cambridge manager John Beck was reluctant to offer Humphreys a new contract until he had seen him play.

[20] Hartlepool United manager Chris Turner, a former Wednesday goalkeeper, then offered Humphreys the chance to train with the club.

Shortly after, Humphreys signed a new contract with the club, much to the dismay of Cambridge fans, who wanted him to stay and described him as "a big loss".

However, Humphreys would soon be back in the team and replace Henderson to partner Watson, these two players were already familiar with each other from their days at Sheffield Wednesday.

[23] Humphreys was then moved into central midfield due to the injury of Tommy Widdrington and after impressing played there for the remainder of the season.

[24] Humphreys' first season at the club would end in disappointment as he missed the decisive penalty in the play-off semi-final defeat to Cheltenham Town, which cost Hartlepool a place in the Second Division.

In the 2003–04 season, Hartlepool once again made the play-offs, only to go out after conceding two last minute goals to Bristol City, a memory which Humphreys described as more painful than Cheltenham.

During the play-off semi-final against Tranmere, Humphreys had the task of taking a penalty for Hartlepool in sudden death.

This time, he scored and sent Hartlepool through to the play-off final against his old club Sheffield Wednesday at the Millennium Stadium.

Humphreys believes that of all the play-off defeats he has suffered the controversial loss to Wednesday was the hardest to take.

During that streak, Humphreys scored another spectacular goal against Walsall to give Hartlepool the lead in a victory that sent them into second place.

[44] However, these awards proved small in comparison to when Humphreys was honoured by the Queen for making a "significant contribution to local and national life" earlier on in the season.

On 2 August 2011, Humphreys was given a testimonial match against Premier League Sunderland to mark his ten years at Hartlepool United.

[49] On 7 January 2012, Humphreys replaced Luke James 90 minutes into a 2–0 win over Rochdale to make his 500th appearance for Pools.

Humphreys was named on the League One team of the week after scoring in a shock 3–2 win at Sheffield United on 29 December.

He made 25 appearances in the 2014–15 campaign, helping the Spireites to the play-offs, where they were beaten by Preston North End at the semi-final stage.

[56] He made only three appearances in the 2015–16 campaign, but in May 2016 signed a new contract to serve the club as a coach whilst also continuing his playing duties.

[60] Humphreys rejected the opportunity to join the coaching staff at Chesterfield and instead signed with Northern Premier League Division One South club Sheffield.

[64] In July 2018, Humphreys completed his first full Ironman Triathlon, raising £3,000 for Sheffield Children's Hospital and Alzheimer's Society in the process.
