Hayden Mullins

Loan to Reading On 15 March 2012, Mullins signed for Reading on loan for the 2011–12 season. He made seven appearances for Reading as they were promoted to the Premier League.

Birmingham City and loan to Notts County On 12 July 2012, Mullins signed for Birmingham City on a two-year contract on a free transfer. He made his debut in the League Cup first round against Barnet, and kept his place for the opening match of the 2012–13 season, a 1–1 draw at home to Charlton Athletic. He scored his first goal for Birmingham in a 2–2 draw with Nottingham Forest on 15 September.

On 31 January 2014, Mullins joined Notts County on loan until the end of the 2013–14 season. He made his debut the next day as a second-half substitute as County lost 2–0 away to Preston North End. Playing at centre back, he made a crucial clearance in the final game, away at Bolton Wanderers, that contributed to Birmingham City retaining their Championship status via Paul Caddis' stoppage-time equaliser. Birmingham confirmed he would be released when his contract expired at the end of the 2013–14 season. He finished his Birmingham career having scored twice in 39 appearances in all competitions.

Notts County On 5 June 2014, Mullins rejoined Notts County on a one-year contract.

International career Mullins made three appearances for the England under-21 team in 1999, against Poland in March, Hungary in April and Bulgaria in June.

Coaching career After retiring as a player, Mullins joined Reading in a role that saw him oversee the development of the club's players who were out on loan. In July 2016, he joined Watford as assistant to under-21 coach Harry Kewell, later progressing to management of the under-23 team. In December 2019, Mullins was named as temporary manager of Watford after Quique Sánchez Flores was sacked. He managed two games as interim manager; a 2–0 away defeat by Leicester City and a goalless draw at home to Crystal Palace. Mullins took charge against Crystal Palace while newly appointed manager, Nigel Pearson watched from the stands.

In July 2020, he was again placed in temporary charge following the dismissal of manager Pearson. His first game in charge following Pearson's dismissal resulted in a 0–4 defeat to Manchester City. This result, coupled with Aston Villa's win later the same day, dropped Watford into 18th place in the league and a relegation position. Watford were relegated to the Championship on the last day of the season following a 3–2 defeat by Arsenal. On 1 September 2020 he left the club.

On 3 September 2020, Mullins was announced as assistant head coach to Steve Ball at Colchester United. In February 2021, Ball was replaced by Wayne Brown as first team coach. After a run of poor results, Brown was in-turn replaced by Mullins on 31 March 2021. On 13 May 2021, Mullins was appointed head coach of Colchester on a permanent basis. On 19 January 2022, Mullins was sacked as head coach after a run of poor results.

He coached the Turks and Caicos Islands national football team in March 2023.

On 26 July 2023, Mullins was unveiled as the new U21 Head Coach at Fulham. On 16 May 2024, he led Fulham U21s to the Premier League Cup, defeating Tottenham Hotspur U21s 4–0 in the final.

On 31 July 2026, Mullins was appointed manager of EFL League Two club Newport County.
