But former umpire Ray Chamberlain is adamant the Hawthorn tall utility has no case to answer.
The MRO findings from this game will be released on Saturday afternoon.
Late in the first quarter, Stewart was fighting for the ball when Sam Butler tackled him.
Chol then also laid a tackle on Stewart and the Geelong star's head hit the MCG turf hard.
Stewart immediately left the ground and was subbed out with concussion.
But Chamberlain said on ABC Radio that Chol had done nothing wrong.
"It (the Butler tackle) is actually part of what brings Stewart forward and towards the ground," Chamberlain said.
"Chol's tackle? Legal. There's no rotation, he doesn't place Stewart's head in a vulnerable position ... I don't think there's any case to answer here for Chol.
"I just think it's an unfortunate set of circumstances that's led (to) his head hitting the ground.
"I don't see that Chol will have a case to answer here."
Chamberlain was asked how the Chol-Stewart incident compared to Paul Curtis's three-game ban earlier this year after his tackle on Port Adelaide opponent Josh Sinn.
North Melbourne unsuccessfully took the case to the tribunal.Â
"Different tackle, different level of force - so we talk about excessive force and driving the player forward," Chamberlain said.
"In this instance, Tom Stewart is going forward and to ground by his own volition in the initial tackle."
