Carter-Vickers has featured in 13 of Celtic’s 15 games this season, so his absence will be a big blow for Rodgers’ side. But it also allows opportunities for others.

Celtic are hardly short of centre-backs – Trusty, Murray, Hayato Inamura and Jahmai Simpson-Pusey all available for the manager to choose from – but they seem to be short of central defenders Rodgers is keen on.

Trusty has been struggling with injury this season and has only played 62 minutes this term, while the inexperienced Murray has only made three appearances.

Inamura, who joined this summer from Japanese side Albirex Niigata, has made just one appearance and that was in a 3-0 win over Livingston in August.

And he has only played once for the B team since Rodgers claimed the defender was “not quite at the level” required to start for Celtic.

There’s also Simpson-Pusey, who joined on loan from Manchester City towards the end of the summer window but has also only played once for the B team.

If Rodgers is to call upon either of the latter two it will have to be for domestic games only as neither was included on the Parkhead club’s European squad list.

So Rodgers has a decision to make. Does he continue with Scales as his main centre-back and add any of the four alongside him? Or, does he change it up and try out different pairings with the four other defenders he has to choose from?

The manager will have to choose quickly and with a game against league leaders Hearts on Sunday, he can’t really afford to get it wrong.
