After a single season back in the Premier League, QPR were relegated after a 6–0 away defeat to Manchester City on 10 May 2015, Green's fourth relegation from the Premier League. Earlier in the season, on 26 December, he saved an early penalty in an eventual 2–1 loss to Arsenal, as his teammate Eduardo Vargas pointed out which way fellow Chilean Alexis Sánchez was likely to shoot. After starting 2015–16 as QPR's first choice goalkeeper, Green was frozen out the starting line-up one match after the arrival of new manager Jimmy Floyd Hasselbaink due to a clause in his contract triggering a contract extension if he played 30 Championship matches. With QPR wanting to reduce the wage bill, Green left the club upon the expiry of his contract at the end of 2015–16, after a move to Premier League club Crystal Palace fell through in the January transfer window. On 6 July 2016, Green signed a one-year contract with Championship club Leeds United. On 7 August 2016, Green made his Leeds debut against QPR in a 3–0 defeat, in which he failed to punch a ball from a corner leading to a Sol Bamba own goal. Green was the match winner in the next match on 10 August 2016 in the League Cup against Fleetwood Town, when he saved a penalty from Fleetwood's Eggert Jónsson in a 5–4 penalty shoot-out victory after a 2–2 extra-time draw His first clean sheet came on 20 August 2016 in a 2–0 win against Sheffield Wednesday. On 20 November 2016, Green committed a high-profile error when he dropped the ball under his crossbar onto the foot of Newcastle United striker Dwight Gayle to tap the ball home in a 2–0 defeat. On 17 December 2016, Green kept his 8th League clean sheet for Leeds, this equalled the tally already for Leeds' clean sheet for the whole of the previous 2015/16 season with goalkeeper predecessor Marco Silvestri. On 25 January 2017, Green kept his 6th consecutive clean sheet for home matches at Elland Road in a 2–0 win over Nottingham Forest. After making his 600th league appearance, on 26 February 2017, Green saved a penalty from Sheffield Wednesday striker Jordan Rhodes in Leeds' 1–0 victory. After impressing during his first season at the club, on 18 March 2017, Green signed a new one-year contract at the club. Green started the 2017/18 season under new Head Coach Thomas Christiansen as the club's second choice goalkeeper behind new signing Felix Wiedwald, and made his only appearance of the season on 22 August 2017 in Leeds' 5–1 League Cup victory against Newport County.
