The background is the drama in the Champions League match between Liverpool and Atlético.
When Virgil van Dijk decided in the 92nd minute and completed Liverpool's 3–2 win, Simeone lost his temper. He reacted against a group of home supporters and was finally led away by officials, before being sent up to the stands.
Uefa's disciplinary committee assesses his behavior as "unsportsmanlike conduct". The penalty means that Simeone is forced to follow Tuesday's home match in Champions League against Eintracht Frankfurt from the stands.
Simeone himself is remorseful after the suspension.
First and foremost, I regret my part in what happened. We do not have the right to react in that way and it does not look good when we do, says the 55-year-old, according to BBC.
Liverpool, in turn, has been punished with 4,000 euros, equivalent to just over 40,000 kronor, after objects were thrown onto the pitch from the stands.
