The French midfielder was involved in a minor bust-up for Celtic today.
Neil Lennon's side dropped two points following a fiery 1-1 draw at Hibernian.
Ryan Christie cancelled out an early own goal from Kristoffer Ajer as Celtic and the Easter Road side shared the spoils.
But were the Hoops fortunate to finish the game with 11 men?
Ntcham was booked in the first half for an altercation with Josh Vela, and Stewart claims that the Frenchman could've easily gone for his aggressive reaction.
He told BBC Sportsound: "Olivier Ntcham is lucky to get away with this. Josh Vela's niggled away at him, but Ntcham ran right into Vela, and then he raises his arms.
"I don't think he catches him in his face, but he's not far away. Two bookings is a classic case of just punishing the two players, but Ntcham was the aggressor there."
Stewart may have a point. The incident happened right in front of referee Kevin Clancy and for him to dole out two yellow cards instead of a red to Ntcham was a touch questionable.
Hibs boss Paul Heckingbottom, who was sent from his touchline, was left fuming with the decision to only book the former Manchester City product - a £4.4 million signing in 2017 - and told The Record afterwards: "You watched it - 100 per cent. That's probably the most frustrating thing of the whole day. "
