Gervinho, 24, was given a straight red card for slapping Magpies midfielder Joey Barton after an altercation in Newcastle's penalty area.
Barton was given a yellow card for his role in the melee, as he had initially dragged the Ivory Coast winger off the ground after an apparent dive from the Arsenal star. Because he had been dealt with during the game, the controversial midfielder has escaped any punishment in the aftermath of the feisty encounter on the opening day of the Premier League season.
Song, however, has been charged with violent conduct and given a ban for stamping on Barton's leg, an incident the referee did not see at the time.
Arsenal has accepted the ban given to Song but will appeal against the severity of the suspension handed to former Lille winger Gervinho.
