Josh Clarke

Glenavon On 8 April 2022, Northern Irish club Glenavon announced the signing of Clarke. He had been brought in on a short-term, emergency deal, following the departure of Declan Brown and the suspension of James Taylor. He made his debut, as a 17 year old, a day after signing, in a NIFL Premiership game against Ballymena United. After Glenavon defender Danny Wallace was sent off for a foul inside the penalty area, Clarke saved the resulting penalty from Leroy Millar as Glenavon went on to win 3–1. He made five further appearances, including Glenavon's 2–0 away loss to Glentoran in the UEFA Europa Conference League play-offs, in which he made a number of saves. Clarke received the supporters' Player of the Month Award in April 2022.

Celtic Clarke moved to Scotland to join Celtic, signing an initial two-year deal in August 2022 and being assigned to the club's B Team. He notably saved four penalties in Celtic B's penalty shoot-out win against Rangers B in the final of the Glasgow Cup, garnering national coverage for his performance.

Loan to Airdrieonians On 5 August 2023, Clarke was sent on a one-game emergency loan to Scottish Championship side Airdrieonians, following the absences of first-choice goalkeeper Josh Rae and player-goalkeeper coach David Hutton. He made his debut the same day, as Airdrieonians lost 2–1 to Dunfermline Athletic, before returning to Celtic.

Loan to Ayr United On 24 February 2024, Clarke extended his contract at Celtic and Ayr United announced that they had signed Clarke on a loan deal until the end of the season. He made a total of 22 appearances for Ayr United over two spells.

Loan to Partick Thistle In July 2025, Clarke joined Scottish Championship club Partick Thistle on a season long loan. The keeper made his debut in a 1–1 league draw with Greenock Morton, going on to make 42 appearances in all competitions, keeping 14 clean sheets. Clarke, alongside fellow Celtic loanee Ben McPherson, agreed a pre-contract deal to join Partick Thistle on a permanent basis in February 2026, coming into effect at the end of the season.

Doncaster Rovers Despite joining Partick Thistle permanently after signing a pre contract agreement, on 7 July 2026, it was announced that Clarke had joined EFL League One club Doncaster Rovers on a season-long loan deal with the option to make the move permanent in January, for an undisclosed fee.

International career In 2019, Clarke was selected to play for Sweden's under-17 team in two friendly matches against Norway and Finland.

In late 2020, he was called up for an England youth training camp at St George's Park. In March of the following year, he featured in a hybrid friendly for the England under-17 team, coming on as a first-half substitute for James Beadle in a 2–1 win over the under-23 side of Watford. In August 2021, he featured in a 2–0 friendly win over Hungary for the Republic of Ireland under-18 side. He received his second call-up for Northern Ireland in their 2022 UEFA European Under-19 Championship qualification campaign.

In March 2022, Clarke was called up to the senior Northern Irish team for the first time at the age of seventeen, but remained on the bench as Northern Ireland beat Luxembourg 3–1 in a friendly. He was called up again in May of the same year, ahead of UEFA Nations League fixtures the following month against Greece, Cyprus and Kosovo, but again did not feature. After a strong start to his loan spell at Partick Thistle, Clarke was recalled to the senior Northern Ireland squad in November 2025.
