The Leeds United striker caught a left-hand from the Tunisian in his final game for Motherwell.
However, the game is best remembered for what happened afterwards.
Lee Erwin of Motherwell went to shake hands with Rangers' notorious hothead Bilel Mohsni. The Tunisian ignored him and Erwin shoved him in the back. In classic Mohsni fashion, he kicked Erwin before leathering him with a left hook to the jaw.
Now Mohsni has been handed his punishment. He will be banned for seven games for 'excessive misconduct' according to the BBC.
Who these seven games will be for remains to be seen. Mohsni is a free agent after leaving Rangers this summer.
As for Erwin, he escaped with just a yellow card for his sins and will be free to start his career with Leeds United as soon as possible.
The striker, who sustained a cut to the face from the fracas, signed for Leeds from Motherwell this month on a free transfer, with a compensation fee to be arranged via tribunal.
Erwin will be hoping to get punched a lot less playing for Leeds.
