Celtic defender Cameron Carter-Vickers was rested for the midweek trip to St Johnstone due to fatigue, manager Martin O'Neill confirmed. The Scottish champions secured a 1-0 victory at McDiarmid Park on Tuesday night with a goal from Mika Baur, moving them three points clear at the top of the Premiership.

O'Neill told BBC Sport the decision was precautionary. "I thought there was, just for energy, I thought the last stages of the game on Saturday night, I thought he was wilting," the manager said. "He's just feeling a little bit sore, which is no surprise." The American centre-back has a history of injury issues, but this absence was purely about managing his workload.

How did Celtic cope without their key defender?

Celtic kept a clean sheet in Perth despite Carter-Vickers' absence. Dane Murray, who has faced criticism recently, partnered Liam Scales in central defence and delivered a solid performance. Murray made no significant errors and helped the back line handle St Johnstone's limited attacks. This demonstrated the squad's defensive depth ahead of a critical period of fixtures.

The team's current defensive record is strong, with only eight goals conceded in 12 league matches this season. You can view the full defensive statistics on our stats page. Carter-Vickers himself has been a mainstay, starting 10 of those 12 Premiership games prior to this rest.

What's next for Celtic and Carter-Vickers?

The immediate focus shifts to a massive League Cup quarter-final against Rangers at Ibrox this Sunday. O'Neill expects Carter-Vickers to be refreshed and available for selection for that match. Following the derby, Celtic host Ferencvaros in their Europa League group stage opener next Thursday, before another Glasgow derby at Celtic Park in the league the following weekend.

This packed schedule makes squad management essential. The manager must balance domestic and European commitments while keeping key players fit. The full list of upcoming matches is available on our fixtures page.

Who stepped up in Carter-Vickers' place?

Dane Murray's competent display provides O'Neill with a reliable backup option. The 22-year-old academy product has made five appearances across all competitions this season. His performance against St Johnstone, where he completed 92% of his passes and won all his aerial duels, will boost his confidence.

It also lessens the immediate pressure to rush Stephen Welsh back from his own injury issue. Welsh remains on the sidelines, but the club's current injuries list shows progress is being made. Murray's showing means Celtic can afford to be cautious with Carter-Vickers' recovery, ensuring he is fully fit for the more demanding challenges ahead.

The 1-0 victory, secured by Baur's 67th-minute strike, was far from a classic performance. But it achieved the primary objective of three points. Celtic now turn their attention to Ibrox, where they will aim to reach the League Cup semi-finals. Carter-Vickers' expected return will be a significant boost for that match on Sunday, 13 September 2026.
