Two key Celtic men missing from training ahead of Falkirk Premier Sports Cup clash

Two key Celtic defenders are reportedly missing from training this morning ahead of the Premier Sports Cup clash with Falkirk.

The Hoops face John McGlynn's Championship side in the final quarter-final on Sunday and will hope to keep up their relentless early season form which has seen them scoring 14 goals in five games while conceding NONE and then thumping Slovan Bratislava 5-1 on Champions League duty.

They will obviously be heavy favourites against the Bairns but the second tier outfit will have a serious go and are unbeaten in the Championship after going through the whole of the previous League One campaign without losing. And Celts' task could become slightly difficult with two of their back four possible doubts.

Neither Cameron Carter-Vickers or Alistair Johnston were present at training this morning, reports the Scottish Sun. And from the early pictures that have emerged from the session, neither are seen.

It could see Auston Trusty handed his first start at centre half after a debut from the bench midweek, while Anthony Ralston would come in at right-back if Johnston doesn't make it. However, there was a similar story involving Cameron Carter-Vickers ahead of the derby against Rangers and he ended up taking his place in the XI. He was though seen with a protective boot after that game.
