The Swiss Football League’s disciplinary body decided that the Super League club owner would have to pay 100,000 Swiss francs (103,000 dollars).
The disciplinary body also added that he has to stay away from stadiums for the punitive period, with immediate effect.
Constantin had slapped Rolf Fringer, a commentator and former Swiss national team coach, after Sion had played Lugano on Sept. 21.
Report said when Fringer fell to the ground, Constantin kicked him.
The disciplinary body said Constantin had committed a “clear and grave violation of the rules of conduct” and had “discredited the values of football.”
Video footage of the incident showed the club owner going berserk on the sidelines after Fringer had called Constantin “a narcissist with zero empathy.”
