Cameron Carter-Vickers could potentially miss Celtic's derby clash against Rangers this Saturday through injury.
The American international went down with a knock during the Hoops' away encounter at Dundee this afternoon.
The 25-year-old could be seen clutching his hamstring as he received medical attention on the field.
Brendan Rodgers took no chances as he substituted the centre-back just before the hour mark. It remains to be seen whether he was taken off by necessity or for precaution.
Stephen Welsh was sent on in place of Carter-Vickers - who did manage to walk off the pitch.
The former Tottenham defender has struggled with injuries throughout 2023, spending several months on the sidelines at varying points.
Rodgers will undoubtedly be asked for an update on the defender following today's match.
Meanwhile, Matt O'Riley is reportedly happy at Celtic amid mounting interest from European giants Inter Milan.
The Daily Record reports that the Serie A side will be told where to go should they firm up their interest in the 23-year-old.
Last week it was revealed that the Italian league leaders had identified the Denmark international as a top target for the January transfer window.
Inter are said to ideally want a loan for the remainder of the season before agreeing to an obligation to buy in the summer. This figure would be eight figures.
O'Riley is contracted at Celtic Park until the summer of 2027, so Celtic is in a strong position to command a sizable fee should he move on.
The report states that O'Riley is aware of the interest from Inter, but he is currently settled and happy to remain put in Glasgow for the time being.
O'Riley signed for the club under Ange Postecoglou two years ago for £1.5m from MK Dons.
He's proved to be a hit since, however, has taken his game up a notch under Rodgers this season by scoring nine goals and assisting his teammates on eight occasions so far.
