Celtic manager Martin O'Neill has been hospitalized following a "small procedure," the Scottish Premiership club announced. The 74-year-old is expected to be released from the hospital within the next day or two.

Details regarding the nature of the procedure have not been disclosed. Celtic released a statement on social media addressing speculation and confirming O'Neill's hospitalization. The club also conveyed O'Neill's gratitude for supporter well wishes and requested privacy for him and his family.

O'Neill was appointed permanent manager in June, signing a one-year contract. This followed two interim spells last season, during which the team secured a Scottish Premiership and Scottish Cup double.
