Union Berlin coach Nenad Bjelica was suspended for three matches and fined 25,000 euros ($27,075) on Thursday after shoving Bayern Munich's Leroy Sané, the German Football Association (DFB) said.
The Croatian coach was sent off in the 74th minute of Wednesday's 1-0 Bundesliga loss to Bayern after pushing Sané.

The player had gone to Bjelica to get the ball near the Union bench to take a throw-in.
He pushed the ball out of the coach's hands and Bjelica then put his hands on the Germany international's face twice, pushing him away.
“Nenad Bjelica was suspended for the next three league matches and fined 25,000 euros for unsportsmanlike behavior,” the DFB said in a statement.
Bjelica, who took over in November, will now miss the Bundesliga games against Darmstadt 98, RB Leipzig and Mainz.
Union, who finished fourth last year to qualify for the Champions League, are currently in 15th place with 14 points, three clear of the relegation play-off spot.
