Bayer Leverkusen midfielder Michael Ballack
Former Chelsea star Ballack, 34, made the insult after last week's 2-0 win over Schalke when fans delighted by the win beckoned him over and encouraged him to chant through a megaphone after the game.
He apologised the following day but the Federation took a dim view and called the midfielder to account.
Ballack's enthusiasm got the better of him as he was making a rare start after an injury-plagued season which has seen him marginalised of late in the German national side.
He also missed last summer's World Cup through injury.
