Martin O'Neill in hospital after Celtic's opening win

Celtic have issued a health update confirming that manager Martin O'Neill has been taken to hospital, according to Mirror Football.

O'Neill was in the dugout on Monday as Celtic began their Scottish Premiership title defence with a 1-0 home victory over Dundee. No details about his condition have been disclosed beyond the club's statement.

The update comes as a surprise given that the Northern Irishman appeared to lead his side through the full match. Celtic have not indicated how long O'Neill might be unavailable, and no further comment has been made at this stage.

For now, fans will hope for a swift recovery while related match highlights from the win over Dundee can be found on this site.
