Celtic did just enough to get all three points against Kilmarnock, a team sitting at the bottom of the Premiership. A goal from Liam Scales sealed the 1-0 win for the Hoops.

Of course, this was not the confidence-boosting win the fans would have been hoping for. Once again, there were question marks about Martin O'Neill's selection coming into the game and going out of it as well.

Unfortunately, there are more reasons to be worried if you are a Celtic supporter coming out of the game as it looks like one of the players could be out of action for a while.

The Celtic midfield has been a problem for them this season. And it looks like arguably their best performer in the middle of the park could be out for a while.

As reported by The Celtic Way, when asked about the knock Mika Baur had picked up, O'Neill said: "Yeah, he's in the treatment room at this minute. His ankle is very sore and we don't know the damage just at this minute. I assume that he'll probably wait until tomorrow to get a scan.

"Gosh, I'm hoping that he would not be out for terribly long. I just don't know at the moment because he's been brilliant for us."

Obviously, that is a worrying sign if you are a Celtic fan. One can only hope that the results of the scan turn out to be positive and that Baur does not end up needing to spend much time on the sidelines.

Celtic might not be in a position where they can deal with the absence of Baur at the moment.

Callum McGregor's performances have been nowhere near up to the mark. And while Benjamin Nygren puts up great numbers, his overall game is not the most impressive by any stretch of the imagine.

Baur is the engine in the middle of the park for Celtic and quite tidy with the ball at his feet as well. He is a full German international for a reason.

Baur has been one of the few positive signings that Celtic have been able to pull off in recent times. While Camilo Duran has quite clearly been the star of the show for the Hoops this season, on the occasions the team has done well, the midfielder has been a valuable addition to their midfield, which lost both Arne Engels and Reo Hatate in the summer, with Paulo Bernardo leaving on loan as well.

If Baur really needs to spend a lengthy spell on the sidelines, the Hoops will miss him dearly. In fact, it could be the last straw and what is already a campaign that looks to be falling apart.
