Martin O'Neill is in hospital after Celtic confirmed he had undergone a small procedure. The club say he is expected to be released in the next day or two, but his place in the dugout for Sunday's trip to Kilmarnock has not been confirmed.

Celtic's update on O'Neill

The club's statement was direct. Celtic said: "In response to speculation, we can confirm that Martin O’Neill has undergone a small procedure in hospital."

They also added: "We would envisage Martin being released from hospital in the next day or two and on behalf of Martin, we would like to thank supporters for their kind wishes."

That leaves the football part open for now. O'Neill's short stay in hospital is the main issue, and the only immediate question is whether he is fit to be on the touchline at Kilmarnock.

Sunday at Kilmarnock

The uncertainty matters because Celtic have not yet said he will be in the dugout on Sunday. That is the line to watch, not because the club are playing games with the update, but because they have simply not gone that far.

There is also a bit of context around the job he has walked back into. Celtic finished the 2025 Premiership campaign on 82 points, went into the championship round with five straight wins, and ended with a 32 goal difference in that run-in.

That does not settle the Sunday question, though. It just shows the standard around the team while the club wait on the manager's recovery and a final call on whether he travels to Kilmarnock.
