Green began his career with Brockenhurst and Christchurch, working under Graham Kemp, before moving to Conference South club Eastleigh for a trial in summer 2009. He won a contract at the club after impressing in pre-season friendlies and the South West Challenge Cup, but did not play a competitive game for the club. Instead he joined Totton on loan in August 2009 in order to gain experience, before the deal was later made permanent for a £7,500 fee. He played 46 games in 2009–10, scoring once against Bishop's Cleeve, and winning two-man of the match awards, as Totton finished second in the Southern Football League Division One South & West. He also played in the defeat to Cirencester Town in the play-off semi-finals. The 2010–11 campaign would be one of the most successful in the club's history, as they topped the division after finishing just two points ahead of Sholing. In May 2011 he won the Hampshire Senior Cup with Totton, following a 3–1 victory over Sholing at St Mary's Stadium.
Port Vale
Green had trials with Reading, Millwall, and Wycombe Wanderers, before he was signed as a 22-year-old by Micky Adams' League Two side Port Vale in July 2011. He described the move into professional football as "a dream come true". He made his debut on the opening day of the 2011–12 season, as Vale drew 2–2 with Crawley Town at Vale Park. He played four further games, before he returned to Eastleigh on a one-month emergency loan deal on 20 October.
Eastleigh
He made his Eastleigh debut on 22 October 2011, scoring in 3–0 win over Welling United, also picking up the man of the match award. As his loan spell was coming to an end, it was revealed that Green had asked to have his Port Vale contract terminated so that he could move closer to his family, and the club 'reluctantly agreed' to his request. He played 24 league games for Eastleigh in 2011–12, as the club posted a mid-table finish. They reached the play-offs in the 2012–13 season, with Green playing 37 league games, before being knocked out at the semi-final stage after a penalty shoot-out defeat to Dover Athletic at the Crabble Athletic Ground. He made 45 appearances in the 2013–14 campaign as Eastleigh won promotion as divisional champions. He scored three goals in 34 league games in the 2014–15 season to help the "Spitfires" to secure a place in the Conference Premier play-offs. He played 39 games in the 2014–15 campaign, as Eastleigh reached the play-off semi-finals, where they lost out to Grimsby Town. He made 38 appearances in the 2015–16 campaign, as Eastleigh finished in seventh place, five points outside the play-off places. He was released by new manager Martin Allen on 10 February 2017. However, he then returned to the club just 12 days later after Allen was sacked and replaced by Richard Hill. He made 45 appearances across the 2016–17 campaign as Eastleigh posted a 15th-place finish, but surgery on an ankle injury meant that he featured only 18 times during the 2017–18 season as the club moved up to 14th-place under the stewardship of Andy Hessenthaler. He featured 39 times throughout the 2018–19 season, helping Eastleigh to reach the play-off semi-finals, where they were beaten by Salford Cityon penalties. He made 28 appearances in the 2019–20 season, which was permanently suspended on 26 March due to the COVID-19 pandemic in England, with Eastleigh in 17th-place.
