Celtic finally had something to celebrate after a difficult spell, but their return to winning ways has not removed the concerns hanging over Martin O’Neill’s squad.
The Hoops went into Sunday’s trip to Motherwell under considerable pressure after suffering three consecutive defeats across domestic and European competitions. With confidence needing a boost and Rangers having moved above them in the Scottish Premiership table, the pressure to respond at Fir Park was clear.
Two goals and a clean sheet provided the response Celtic desperately needed. However, while the result lifted spirits and temporarily restored them to the top of the league, attention quickly turned towards a potentially damaging setback ahead of their next European assignment.
And Rangers’ recent involvement in Celtic’s difficult run adds another layer to the situation.
Just two hours after the victory over Motherwell, O’Neill delivered an update that could leave Celtic supporters worried about what lies ahead.
Carter-Vickers setback hands Celtic fresh concern

Celtic secured a 2-0 victory over Motherwell thanks to goals from Camilo Durán and Benjamin Nygren, but Cameron Carter-Vickers was unavailable after picking up a strain.
The American defender’s absence forced O’Neill to turn to Dane Murray alongside Liam Scales in central defence. The pair helped Celtic keep Motherwell at bay, allowing the visitors to leave Fir Park with three valuable points.
However, producing a solid performance against Motherwell does not necessarily mean Celtic can afford to lose one of their most important defensive figures for a demanding European fixture.
Carter-Vickers has been a key presence at the heart of the Hoops’ defence, and his potential absence against Benfica could leave O’Neill with another selection headache at a particularly inconvenient moment.
Asked whether the defender would be ready for Thursday’s Europa League encounter, the Celtic manager admitted that a return was far from certain.
“He might not be fit for Thursday. I think he’s got a strain and he’s missing this one.”
O’Neill then revealed that the medical staff had already warned him about the difficulty of getting Carter-Vickers back in time.
“Physios and the medical team have told me that Thursday might be too early.”
Those comments represent a significant concern for Celtic, who are preparing to travel to Portugal for a challenging meeting with Benfica.
Rangers connection adds another twist
The timing of Carter-Vickers’ injury concern is particularly frustrating because his last outing came against Rangers, with Celtic having endured a difficult run against their city rivals.
The defender’s current problem has emerged following that latest Old Firm encounter, leaving Celtic potentially without an important defensive option as they attempt to recover from the damage inflicted by their recent setbacks.
For Rangers, the situation could indirectly represent welcome news. While the Ibrox side are not responsible for Celtic’s team selection, any prolonged absence for an influential defender could complicate the champions’ efforts to maintain their position in the title race.
That possibility is especially relevant given the contrasting demands facing the two clubs.
Celtic have European commitments to navigate alongside their domestic campaign, while Rangers can concentrate on the Premiership after failing to progress through the European qualifying rounds.
O’Neill himself acknowledged that the difference in schedules could give his rivals an advantage over the coming weeks.
“I think that was the point. I think that’s a big advantage for them in many aspects,” he said when discussing Rangers’ lack of European football.
The Celtic manager even admitted that he had wanted Rangers to qualify for their competition, explaining that his reasoning was to ensure they also had midweek matches to contend with.
His comments underline the challenge facing Celtic as they attempt to balance their European ambitions with the need to remain competitive at home.
Celtic must find another solution
Carter-Vickers’ possible absence leaves O’Neill with decisions to make before the trip to Benfica.
Murray partnered Scales against Motherwell, and the clean sheet will have provided encouragement after Celtic’s recent defensive difficulties. Auston Trusty was also among the substitutes, giving the manager another potential option if Carter-Vickers cannot recover in time.
Nevertheless, facing Benfica presents a different test, and Celtic would naturally prefer to have their most experienced defensive options available.
The concern is not simply about one match. With domestic pressure already building and Rangers continuing to compete for the Premiership title, every injury has the potential to affect Celtic’s ability to maintain consistency.
Sunday’s victory was an important step towards restoring confidence, but O’Neill knows the team cannot afford to become complacent after ending their losing run.
Durán’s early goal gave Celtic control at Fir Park, while Nygren’s second-half strike helped secure the points. Jota also made his long-awaited return to action, providing another positive moment for the travelling supporters.
Yet the Carter-Vickers update has placed a question mark over what should otherwise have been a thoroughly encouraging afternoon.
Celtic are back on top of the league, but their next challenge arrives quickly, and O’Neill may have to prepare for it without a central defender who could be crucial to their hopes of getting a result.
Rangers have no direct control over that situation. However, with Carter-Vickers’ latest fitness problem emerging after the recent Old Firm clash, Celtic have been handed another unwanted complication at a time when they need stability more than ever.
