Emanuel Pogatetz has been handed a three-game ban for elbowing Nurnberg's Philipp Wollscheid.
The former Middlesbrough defender was handed the ban after television evidence showed his clashed with Wollscheid.
The incident happened last week and Pogatetz insists he did not commit the offence.
Pogatetz had told Bild: "I was fouled in that moment.
"We both went for the ball and he was trying to block me off. I am trying to get away from him then and unfortunately I hit him then. But it really has not been serious in any way."
