Airdrieonians After stepping out the pro-youth system for several years to play for
Scottish Juniors club
Bathgate Thistle, Ferguson then signed for
Airdrieonians on 15 August 2013. Ferguson formed part of the
Diamonds youth team before making his first-team debut, at the age of seventeen, on the last day of the
2014-15 season versus
Dunfermline at the
Excelsior Stadium. Although considered back-up keeper to Airdrie's number one keeper
Neil Parry in the
2015-16 season, his reputation was growing and on the eve of the
Diamonds Scottish Cup 4th round match with
Dundee United in January 2016, the Tannadice club launched a bid for the player that was rejected by the
Diamonds. The
Terrors had a further bid rejected before another of Ferguson's former clubs,
Hearts showed interest, as Ferguson spent time on trial with the
Tynecastle club, as Airdrie's manager
Eddie Wolecki Black said: "
Rohan is recognised now as one of the hottest young prospects in the game. He sparkled in our recent 1–0 Scottish Cup defeat by Dundee United and relished the experience of training with Hearts. We will need to see what develops in the months to come." Ferguson then signed a new two-year contract, as Airdrie turned full-time and with Parry no longer at the club, Ferguson was the new number one keeper for the
2016-17 season, as he won the League One player of the month award for November 2016. Fergsuon completed the season with the Diamonds having played 45 matches but couldn't help his club to promotion after they lost to
Alloa in the play-off semi final.
Motherwell On Friday 18 August 2017, Ferguson signed for
Motherwell on a three-year contract, although he was immediately sent back out on loan to Airdrie for the remainder of the 2017–2018 season. Youngsters
Jake Hastie and
Luke Watt were also sent out on loan to Airdrie as part of the deal. Ferguson played a further 24 matches for Airdrie on loan and ended up with 80 appearances for the Diamonds. Ferguson's first competitive match for Motherwell was in the
Scottish Challenge Cup, appearing for Well's Colts team versus
East Stirlingshire at the
Falkirk Stadium. On 3 April 2019, Ferguson debuted for the first-team, appearing as a substitute for the injured
Mark Gillespie in a 3–1 defeat versus
Aberdeen.
Linfield (Loan spell) On 19 July 2019, Ferguson moved out on loan to
Linfield for the entire 2019–20 season. Ferguson was released by Motherwell in May 2020.
Queen of the South On 17 September 2020, Ferguson signed a one-year deal with
Scottish Championship club
Queen of the South.
Larne On 8 June 2021, Ferguson signed a one-year deal with
NIFL Premiership club
Larne. He helped Larne to become the first Irish Football League team to qualify for the Europa Conference League in the 2024/25 season, after beating Lincoln Red Imps on aggregate. ==Career statistics==
