The on-loan Bolton player, 19, has been handed a notice of complaint by the SFA after being cited for "punching a player on the opposing team" and "thereafter kicking him repeatedly on the head and body" during Tuesday night's under-20s match at Firhill.
Speaking ahead of their tie tomorrow with Celtic, Archie said: "I got the match official's report yesterday and it does not make good reading.
"I spoke to Gary. He just said the red mist came down and he retaliated. He knows he let himself down. He went in and apologised to the player and the referee.
"I think he will get a lengthy ban but some reports are saying a year out of football.
"I don't know where that is coming from. I have seen a lot of people doing a lot worse than that and get a lot less so I think it's madness."
