The Scottish Premiership match between Celtic and Hearts remains goalless, despite a dominant performance from the reigning champions.
Celtic started the match strongly and Kris Commons tested Hearts goalkeeper Neil Alexander from long range in the fourth minute.
Leigh Griffiths was next to hit the target before Tomas Rogic's shot narrowly missed the right post.
James Forrest came closest to opening the scoring in the first half when his right-footed shot rebounded off the crossbar.
Alexander was called into action once more before half time, as he kept out Nir Bitton's long-range effort.
