Martin O’Neill has revealed Celtic’s early assessment of Mika Baur’s injury after the midfielder was forced off during the 1-0 win over Kilmarnock.

The midfielder was clearly in discomfort as he left the pitch, and O’Neill first confirmed to BBC Sport after full-time that Celtic were preparing to investigate the problem.

“Yeah, we’ll have to see about him.

“He is in pain at this minute. And I think he’ll be going for some scans very shortly.

“But we’ll see how he is.”

O’Neill then offered a further update while speaking to CelticPlayer, revealing the initial view from the club’s medical staff.

“We’ve all gone into see Mika Baur. The physio tells me it might be a heavy ankle sprain. That’s what we’re hoping it is rather than anything else, but it’s too early to say.”

That remains an early assessment rather than a confirmed diagnosis.

O’Neill was careful to stress that it is too soon to know the full extent of the problem, with scans expected to provide a clearer picture.

The German had been heavily involved before his withdrawal.

His challenge on Greg Kiltie led to Kasper Høgh’s first-half goal being ruled out following a VAR review, while Baur later found the net himself before being flagged offside.

He also made several runs beyond Celtic’s forward line as O’Neill’s side tried to find the second goal which would have killed the game.

That goal never came.

Baur’s fitness will now be one of the main issues for Celtic to monitor during the international break.

The club have an initial idea of what the problem may be, but O’Neill’s comments make clear that further assessment is still required before any timescale can be considered.
