Martin O’Neill has revealed that Cameron Carter-Vickers complained of his hamstrings being very tight at half time against Besiktas, and that the plan to bring him off early in the second half was scrapped as Celtic chased the game.
O’Neill said (TCW): “I thought he was very strong. He was complaining about his hamstrings being very tight at half-time and I thought we would give him another 15 minutes.”
The change never happened on schedule. Carter-Vickers stayed on until the 78th minute, when Dane Murray replaced him with the score level, and Celtic went on to win 3-2 in the Europa League on Thursday night.
Three Games Into a Comeback
The context is what turns a tight hamstring into a story. Besiktas was Carter-Vickers’ second start in five days, and his third appearance of a comeback from a six-week muscular strain.
He returned at Hibernian on October 25 and made his first start at Falkirk on November 1. Behind this return sits a longer one: an Achilles rupture in October 2025 cost him most of last season.
O’Neill’s plan, another 15 minutes and then off, was workload management. The match overruled it, and the defender completed 78 minutes on a night Celtic needed him.
He is a cornerstone of this side, 185 appearances into his Celtic career and under contract to 2029. That is precisely why his minutes are being managed at all.
He had a point to prove on Thursday, after his error in the Falkirk match last weekend, and by his manager’s assessment he proved it.
Celtic’s Sunday Question
O’Neill has said nothing about Sunday. There has been no word from the manager or the club on whether Carter-Vickers faces Kilmarnock, and any doubt label attached to him elsewhere is not O’Neill’s.
If Celtic do ease him out, the replacement is already identified. Murray is the man who came on for him on Thursday, and the other senior option is absent, with Auston Trusty away on compassionate leave.
The stakes are not small. Celtic are top of the table, four points clear of Rangers, who hold a game in hand.
What It Means for the USA
Carter-Vickers is not in the United States squad for this month’s Nations League quarterfinals against Haiti. His route back runs through one thing: a clean, sustained run of club minutes.
Nights like Thursday build that case, 78 strong minutes in Europe three games into a comeback. A hamstring setback at this stage of the return is the scenario that buries it.
That is why a half-time complaint in a November Europa League match matters beyond one substitution.
The winter camps are his next realistic window, and places in them will be decided by the minutes he accumulates, and the setbacks he avoids, between now and then.
What Is Known and What Is Not
Known: the hamstrings were very tight at half time, the manager planned an early change, the player lasted 78 minutes, and Celtic won.
Not known: anything about Sunday. O’Neill has made no statement on Kilmarnock, and the club has published no assessment.
The answer arrives with the teamsheet: Celtic against Kilmarnock at Celtic Park on Sunday, kicking off at 4 PM UK time.
