CELTIC take on Kilmarnock this afternoon in what should be an interesting challenge for the bhoys on the dreaded plastic surface.
Tom Rogic has missed out on the tie, coming back from injury and not being risked on the pitch. Elsewhere, Griffiths has a calf strain and will not make the bench for the visit to Rugby Park.
There IS a debut for Vasilis Barks in goal, Scott Bain demoted to the bench for the away day.

Robertson comes into the fold in place of Rogic on the bench for the hoops this afternoon.
Apart from Barkas, it’s the same outfield XI who beat Hamilton comprehensively last Sunday.
Celtic will need to keep the pressure on and hopefully continue to lay down a marker for this season. They got off to a perfect start against Accies, a clean sheet for Barkas today would do him the world of good going forward. The goalkeeper has big gloves to fill after Fraser Forster didn’t return for another loan spell.
Kick-off is at 16:30 on Sky Sports.
