The referee then reversed his call and awarded Mainz a penalty and had to call the players from both teams back onto the field.
A freaky video assistant referee (VAR) decision caused mayhem in a Bundesliga game on Monday night when two teams were ordered back on to the pitch at half time because the referee chose to award a penalty after watching a replay on TV.
There was a further 10-minute delay before the start of the second half as fans threw hundreds of toilet rolls onto the pitch in a protest against Monday evening matches.
De Blasis eventually added a second goal for the hosts late in the game following a mistake by Freiburg keeper Alexander Schwolow.
Pablo de Blasis scored one of the most remarkable goals in Bundesliga history - during the half-time break - as Mainz beat relegation rival Freiburg 2-0 amid fresh protests against Monday night games.
Freiburg's Marc-Oliver Kempf was ruled to have handled the ball seconds before the whistle, and he and his team-mates were called back from the dressing room for the penalty to be taken.
As the players departed the pitch, Winkmann was told to consult VAR and ran over to the other side of the pitch to watch the replay on a monitor.
Referee Guido Winkmann initially allowed the game to play on, denying Mainz a penalty, before blowing for halftime shortly thereafter.
The ref maybe shouldn't have sent them off as quickly, it depends on how quickly VAR contacted him.
English football has had its fair share of problems and controversies with the infamous VAR system this season, but nothing comes close to the extraordinary scenes that occurred over in Germany in the Bundesliga clash between Mainz and Freiburg on Monday night.
I still think the penalty is debatable.
