As the Glasgow derby looms, Celtic’s preparations have taken a concerning turn.

The absence of the American international, who exited the Dundee match due to hamstring tightness, has become a focal point of speculation just a day before the crucial showdown with Rangers.

While it’s possible Celtic were merely exercising caution, opting not to overexert Carter-Vickers ahead of the high-stakes game, his absence from training was a significant development.

Brendan Rodgers has now confirmed he will not play any part via Andrew MacLean.

The situation adds a layer of uncertainty to the match, with Celtic’s defensive strategy now under the microscope. We could be going into a derby with Liam Scales and Stephen Welsh as our starting centre backs.

Gustaf Lagerbielke and Maik Nawrocki have been nowhere to be seen in matchday squads. One of them will now likely get a place on the bench.
