Reo Hatate has been one of the key stars of Ange Postecoglou's dominant Celtic this season.
But there are fears that he could be missing for a concerted period of time at the business end of the campaign. It's after the Japanesee star was forced off early against Hibs with what looked like a hamstring problem.
Aaron Mooy also missed out at Ross County last Sunday as Celtic were in control but laboured a bit to put the Staggies away meaning the normal midfield rhythm was upset. It's unclear if he will be able to face Rangers on Saturday when Celtic can make the title completely safe with a win.
