Celtic are being held by Kilmarnock after an uneventful first half at Celtic Park.
After a quiet opening 10 minutes, it was Kilmarnock central defender Conrad Balatoni who had the game's first chance but his header went wide of the right post.
Leigh Griffiths's shot was stopped by Jamie MacDonald four minutes later before Northern Ireland international Josh Magennis missed the target at the other end.
Tom Rogic shot off target twice in quick succession and Stuart Armstrong missed from long range on the half-hour mark.
Griffiths then shot straight at MacDonald as the teams went in goalless at half time.
