Celtic talisman Kyogo is set to miss a significant run of fixtures after Ange Postecoglou revealed the latest on his star man.
The Japanese international reaggravated a hamstring injury in the 3-1 win away to St Johnstone and appears no nearer to making a return to action.
Celtic face Hearts next week and Rangers the week after as Postecoglou goes in search of title glory in his first season in Scotland.
