With the teams already in the dressing room for half time, the referee called them back out after VAR awarded a penalty on the stroke of half time.
The penalty was scored, to put Mainz 1-0 up against Freiburg, and the players then resumed their half time break. The scorer of the penalty, Pablo de Blasis, is not a fan of the system it seems.
"I don't like it," said De Blasis, 30.
"I like the old football, with more emotions, without the referee on the video stopping the emotions.
"[The Freiburg players] were angry. They didn't understand why the referee decided after some minutes to check the video and they probably didn't want to come back out but the rules are the rules.
"The really strange thing was that the referee told me that when I shoot the half is finished. I didn't have rebounds. Just one chance for me."
