The French league suspended Marseille defender Taye Taiwo for one match on Thursday after he joined team fans in singing an expletive-laced song about archrival Paris Saint-Germain following last month's League Cup final win.
After Marseille beat Montpellier 1-0 to retain the League Cup trophy at Stade de France, Taiwo grabbed a microphone and sang with Marseille fans in a mocking and insulting song about PSG - Marseille's bitterest foe.
The French league gave Taiwo another two games in a suspended sentence in case of a repeat offense, although that was unlikely as Taiwo was set to join AC Milan on a free transfer next season.
The ban takes effect from Monday, meaning the Nigeria left back is eligible for Sunday's trip to Lorient, but will miss the subsequent home match against Valenciennes - depriving him of a farewell ovation from Marseille fans.
The 26-year-old Taiwo, a free kick specialist with a powerful shot, was a fan favorite of Marseille's having scored 25 goals in 269 games since joining the club seven years ago.
Defending champion Marseille was in second place and trailed leader Lille by four points with three matches remaining.
