Celtic manager Martin O’Neill is currently recovering in hospital after undergoing a “small procedure,” the club confirmed on Wednesday. The 74-year-old was in charge for Celtic’s 1-0 victory over Dundee on Monday night and is expected to be discharged within the next day or two.

The club issued a statement addressing speculation about his health, assuring supporters that the procedure was minor and that O’Neill is expected to make a full recovery. They also requested privacy for the manager and his family during this time. While the specifics of the procedure were not disclosed, insiders and club representatives indicated there was no threat to O’Neill’s future with Celtic.

O’Neill signed a one-year contract with an option for a second year in June after successfully steering the club through two interim spells last season. During that period, the former Northern Irish international led Celtic to a league and Scottish Cup double, reinforcing his status as a key figure in the club’s recent successes. He is widely credited with guiding the team to recover from a challenging title race, overtaking Rangers and Hearts in the final stages of the Scottish Premiership campaign.

The manager’s assistant coaches, Shaun Maloney and Mark Fotheringham, are expected to oversee training and preparations in O’Neill’s brief absence. It is anticipated that O’Neill will return to lead the team for their upcoming match against Kilmarnock on Sunday.

The news prompted an outpouring of support from across Scottish football. Former Celtic defender Stephen Welsh, who played under O’Neill before his move to Swansea City, described the manager as an exceptional figure, praising his resilience and experience despite his age. Welsh expressed confidence that O’Neill would recover quickly and return to the dugout to continue the team’s push for success this season. Rangers manager Derek McInnes also conveyed his best wishes, highlighting the mutual respect shared between the two rivals.

O’Neill is regarded as a legendary figure at Celtic, having enjoyed a highly successful first tenure as manager from 2000 to 2005. His return last season came after the departure of Wilfried Nancy, whose brief 33-day spell as manager was described as disastrous by some observers. O’Neill’s leadership has been credited with restoring stability and inspiring the team to maintain its dominance in Scottish football.

Celtic’s interim chairman, Brian Wilson, praised O’Neill’s “leadership, inspiration and success” in a statement, while controlling shareholder Dermot Desmond acknowledged the manager’s enduring contribution to the club. O’Neill himself expressed pride in continuing his role as Celtic manager, emphasizing the privilege it was to lead one of football’s most storied clubs. He will turn 75 in March next year.
