Butler ran down Sydney defender Nick Blakey in the third term of Thursday night's win over the Swans at the SCG.
Blakey's head hit the ground in the incident, which was graded as careless conduct, medium impact and high contact.
Commentator Jason Dunstall said on Thursday night he would be "horrified" if Butler was suspended for the tackle.
"I'd be really concerned with where the game's going if he gets rubbed out for that tackle. I'd be horrified," Dunstall said on Fox Footy.
"I was watching that passage of play and I thought Dan Butler was brilliant the way he stayed in the hunt, because it looked like he was out and he just kept in there, in there, in there.
"And eventually, he makes the tackle, momentum takes him to ground. He's got no option here. I don't know.
"I don't get what the options are there, other than not tackling. And I would have thought if we say don't tackle, well, then we may as well give up the game."
A free kick was paid against Butler.
The Swans backman left the field and was substituted out of the game, but coach John Longmire said Blakey passed his concussion test and he was taken off because of a toe injury.
Butler is the latest player to be suspended this season as the AFL cracks down on tackling, amid heightened concerns about concussion in sport.
