Mainz's Egypt striker Mohamed Zidan has been fined 6,000 euros (7,880 US dollars) by the German Football Federation (DFB) for swearing at rival fans during a German league match.
The DFB found him guilty of unsporting behaviour for shouting "Shit Kaiserslautern!" at visiting fans after scoring the opening goal against them just two minutes into Mainz's 4-0 home victory on February 25.
Zidan has already said he will not appeal the decision by the DFB's disciplinary committee and apologised for his actions to both Kaiserslautern boss Stefan Kuntz and the fans immediately after the incident.
Since transferring from defending German champions Borussia Dortmund in January, Zidan, 30, has scored in each of his five games for Mainz.
The Egyptian can consider his fine relatively low as ex-Germany captain Michael Ballack was fine 8,000 euros in March 2011 for shouting "Shit Cologne!" at their fans while playing for Bayer Leverkusen.
Werder Bremen goalkeeper Tim Wiese was fined the same amount for swearing at Hamburg fans in 2009.
