The Japan international went off with a leg knock during last Saturday’s 5-0 win over Aberdeen after coming off worse in a 50-50 with Dons goalkeeper Kelle Roos.
The 28-year-old has scored 33 goals this season and won a clean sweep of Scotland’s player of the year awards, and he has an impressive record in cup finals, with match-winning doubles in the League Cup in each of his two seasons with Celtic.
Boss Ange Postecoglou said: “Kyogo is progressing. He hasn’t trained yet. The plan is to get him out there tomorrow (Friday) and see how he goes. He is doing some individual stuff this afternoon.
“He always is, but he is still pretty bullish about playing so we will just see how he goes.
“We will be guided by him a little bit. We have done that in the past. He has had a couple of times, whether it’s with his shoulder or in last year’s League Cup final he went in with a hamstring that wasn’t totally healed and scored a couple of goals.
“So I will be guided by him. He is very strong mentally so if he gives us the green light we will put him in there.”
The only definite absentee is Australia midfielder Aaron Mooy, who has been nursing a back problem in recent weeks.
Postecoglou said: “(Alistair) Johnston is fine, he has trained all week and (Sead) Haksabanovic is back in so he is available as well. The only real absence is Aaron Mooy.”
