Slot and assistant Spike Hulshoff confronted Michael Oliver after the final whistle over James Tarkowski’s controversial equaliser.
Liverpool argued there was a foul in the build-up, but Oliver awarded the goal, with VAR upholding the decision.
Slot was shown a red card after shaking Oliver’s hand, raising questions about the nature of his dismissal.
The Premier League initially stated the decision was due to ‘offensive, insulting, or abusive language’ before later deleting their statement.
In the deleted statement, the Premier League said: "Liverpool head coach Arne Slot was dismissed at the end of the Merseyside derby for using offensive, insulting, or abusive language.
“He is handed a two-match touchline ban as a result."
