The Estonia winger signed before his new side's Scottish Communities League Cup final victory over Hearts but did not make the Hampden squad.
Thomas Reilly, David Barron and Darren McGregor remain on the sidelines, though McGregor neared a return to first-team action after his serious knee injury with 90 minutes for the U20s this week.
Celtic, missing captain Scott Brown following his surgery on an adductor problem, will form a guard of honour for the triumphant Saints players before kick-off in Paisley.
"It is out of respect," Hoops manager Neil Lennon said. "I have had it done to myself over the years and it is a nice thing to do.
"They will be quite buoyant after the League Cup win, they will have a vociferous support behind them as well.
"But we have our own targets. We had a great comeback against Aberdeen in our last game; we have started to show what we are capable of and I want to see that from the start on Sunday."
Lennon, who watched his side open up a 15-point lead at the top following a 4-3 fightback win over the Dons, will also be without defender Thomas Rogne (hamstring), while midfielder Joe Ledley is a doubt with a groin complaint.
James Forrest (back) and Adam Matthews (hamstring) are still out but midfielder Victor Wanyama returns from suspension.
