Celtic manager Martin O'Neill remains in hospital after undergoing a 'small procedure', the club confirmed on Tuesday. The 74-year-old is expected to be released in the next day or two, with Celtic asking for privacy for O'Neill and his family during this time.

What happened to Martin O'Neill?

O'Neill, who signed a one-year deal in June after two interim spells last season, underwent the procedure on Monday. Celtic did not disclose details about the nature of the operation but assured supporters that the manager is recovering well. The Northern Irishman was in the dugout on Monday as Celtic started the new Premiership campaign with a 1-0 home win over Dundee.

Why it matters for Celtic

O'Neill's return to Celtic last October marked a significant moment for the club, 20 years after his first successful spell in charge. He led the team to a Scottish Premiership and Scottish Cup double, securing his eighth and ninth major honours with the club. With the new season approaching, O'Neill's leadership will be crucial as Celtic aim to close the three-point gap to league leaders Heart of Midlothian.

What comes next for Celtic?

Celtic finished the 2025 season in third place with 67 points, boasting a recent form of five consecutive wins. Their last result was a 3-1 victory over Heart of Midlothian on May 16, 2026. With Jota currently sidelined, O'Neill's focus will be on maintaining the team's momentum and preparing for the upcoming fixtures.
