Borussia Dortmund's 1-0 win at Bayer Leverkusen in the Bundesliga was interrupted for eight minutes Sunday after the home side's coach refused to be sent to the stands.
Pierre-Emerick Aubameyang's 64th-minute goal was enough for second-placed Dortmund to restore the eight-point gap behind Bayern Munich.
But referee Felix Zwayer sent Roger Schmidt off for complaining vociferously over the positioning of a free-kick in the build up to the goal, when Leverkusen striker Stefan Kiessling lost the ball and fouled Sven Bender. Matthias Ginter took a quick free kick from where the ball rolled to Erik Durm, who crossed for the onrushing Aubameyang to shoot to the unguarded net.
Zwayer ordered both sides off the pitch when Schmidt made no sign of moving, prompting widespread confusion among players and fans.
